Bear Creek, the Svea 123R stove, and the Edelweiss Cookset

I wanted to get out yesterday, but I didn't have the time to do something long, and I've been having foot problems.  So, to Bear Creek I decided.

Now, not only did I want to get out for some exercise and to get away from "civilization" but I also wanted to try out my "new" (to me) Edelweiss cookset that was given to me by "hikermor" from California.
The Edelweiss Cookset
But first, let's get to Bear Creek.  From Azusa, take Highway 39 north to the confluence of the West and North Forks of the San Gabriel River.  There are two parking lots and a picnic area here as well as a pit toilet.  No potable water is available, but of course the river is very close by if you have the means to treat the water.  Park at one of the two lots or along the side of the highway if the lots are full.  Don't forget to post your parking permit ("Adventure" pass).

From the parking area, proceed on foot up the paved road that goes west along the south bank of the West Fork of the San Gabriel River.  Go west for about one mile.  After about a mile, you should see this sign with an arrow on top pointing north across the river.

If the water is really low, you can just wade or rock hop across the water directly to Bear Creek, but there is an easier way.  Proceed another 100m or so west and cross a bridge.  After crossing the bridge, turn left, descend to the river bank, and go underneath the bridge.  Follow the river 50m or so downstream to the confluence of Bear Creek.

In the above photo, Bear Creek is flowing into the West Fork just behind the trees on the left side of the frame. OK, so let's start heading up Bear Creek.
Heading up Bear Creek
The trail is in pretty decent shape and is reasonably followable.  Someone has painted green arrows in a few spots which, while ugly, do correctly point the way in those sections where the trail is a little hard to spot.  As with most streamside trails, expect a lot of water crossings.

En route, we encountered some really big Canyon Live Oak (Quercus Chrysolepsis) acorns.  Look at the size of this acorn cap compared to my hand.

One more stream crossing, and my friend Will and I arrive at Lower Bear Trail Camp

After crossing the creek, we climb the opposite bank to the little stream side "bench" that hosts Lower Bear Trail Camp.

Apparently someone staying here had a lot of time on their hands!

Also interesting was this "fire can" made from a 55 gallon (208 liter) steel drum.  The drum had air vents cut into it with a cutting torch, and carrying handles have been attached to either side.  I just can't imagine who would drag such a thing out into the woods through all those stream crossings!  Unfortunately, the can is being used as a trash container, and there is no trash collection service here.

Well!  There's our journey, and there's our camp.  Now, let's have a look at that cookset.  The best information that I have is that this cookset came out in the 1950's and was produced through the 1960's.  This particular set belonged to a former Search and Rescue team member.  No telling where it has been, but it sure looks like it's been to a lot of places!

The cookset's lid has graduated "steps" so as to fit the two different pot sizes that come with the set.  Unfortunately, one of the pots had reached "end of life" before the set came to me.  I believe I now have only the smaller of the two pots that originally came with the set.

Turned upside down, the cookset's lid can be used as a pan.
The inside of the cookset's lid
So, now that the lid's off, let's see what's in the set.  Inside is the stove, cookset base, and windscreen.  I've also added some stuffing to keep things from rattling.  You can't see it because it's wrapped, but there's a set of pot grippers in there.  There's also room for a bottle of priming alcohol, a lighter, and a spoon.
The interior of the cookset
The cookset is meant to be used with the short version of the Primus 71 stove.  Unfortunately, I don't own such a stove.  Here I've substituted a Svea 123R which is roughly the same height.

 Note that a Svea 123R says only Svea 123 on the tank.  There is no "R".

So, what's the difference between the original Svea 123 produced by Sievert starting in 1955 and the version produced from the 1970's onward after Optimus bought the rights to the Svea name in 1969?  The main difference is that the Svea 123R has a cleaning needle built into the burner. When the valve is opened all the way, the needle moves up into the stove's jet cleaning out any soot or other blockages.  The original Svea 123's had no built in needle.  Instead a separate "pricker" was sold with the stove.  One unscrewed the burner bell and inserted the thin wire of the pricker into the orifice of the jet in order to remove blockages.  While a built in needle is easier to use when the stove is hot and is not as easy to lose as a separate needle, the addition of the needle added more moving parts and limited the range of the valve.  While many people do like the "improved" version of the stove, there are also many who insist the original version of the stove is the better version.  I myself generally prefer the original version so long as good quality fuel is available.  If the fuel were of questionable quality, the Svea 123R is probably the better version.

Well, if the engraving on the tank for both models is the same, how does one tell the two apart?  There are several ways by which one can quickly distinguish the two versions.  First, the valve on a Svea 123R protrudes from the burner column at a right angle.  The valve on an original Svea 123 slants downward.

Second, the valve on a Svea 123R is slightly offset to the right.  The original Svea 123's valve is centered.

Third, the regulating key on a Svea 123R has a larger aperture is a close ended wrench.  The regulating key on an original Svea 123 has a smaller aperture and is an open ended wrench.
A typical Svea 123R regulating key is closed ended and has three fittings
There are other more subtle differences, but those three are probably the most visible and most readily identified.  So, next time you're on eBay, why don't you see if you can spot the differences?  After reading this post, you'll frequently know more than the seller!

One more thing about the stove before we get back to the cookset:  The tank cap.  If you see a tank cap with a long extension like the one in the below photo, it's a pump compatible tank cap.  Caps of this type are compatible with either an Optimus mini (straight) or midi (angled) pump.  The pump allows one to add pressure to the stove which can help in getting the stove started in cold weather.  The pump is optional; a Svea 123 or 123R will run just fine without a pump if you prime the stove well.

OK!  So, back to the Edelweiss cookset.  In the base of the cookset is a "half moon" clip spot welded in place. 
The clip that secures a short Primus 71 in the stove base of an Edelweiss cookset
  The tank of the short version of the Primus 71 slides under the lip of the "half moon" clip such that the stove is held in place.  As I mentioned, I don't have a short Primus 71, so I'm substituting a Svea 123R.  The Svea 123R's tank does NOT fit into the clip.  However, with a bit of creativity, a Svea 123R can be positioned such that the stove can be used with the cookset.

The cookset's base has ventilation holes on one side.

On the other side is an access portal so that one can operate the regulating key.

Next comes the windscreen.

The windscreen is then emplaced on the base such that the burner of the stove protrudes through the hole in the center of the bottom of the windscreen.

Next, look at the pot.  Note in the photo below the lip around the edge of the bottom of the pot.  The lip fits into the windscreen making for an extremely stable set up.

One can also use a good sized fry pan (i.e. not from the set) with the base and windscreen.

The aluminum of the Edelweiss cookset seems a bit soft to me.  I find that I can bend the pots etc. fairly easily.  Note all the dents from the pot gripper in the photo below.

The whole set up looks like the photo below when everything is in place.  I suppose it looks better to have the lid upright but frankly it's more practical in terms of using the pot gripper to use the lid upside down.

If you look closely at the next photo, you can see the stove blazing away inside the cookset.

Not only is the Edelweiss cookset a very stable set up, it's quite effective as well.
Passing the "tea test" with the Edelweiss cookset.

I haven't done exhaustive side-by-side tests, but my gut feel is that I can heat water a lot faster using the Edelweiss cookset than I can with a Svea 123R in stand alone mode.  I believe the reasons for this ability to heat water more quickly are as follows:  Firstly, the cookset is configured such that the airflow is directed from bottom to top which increases efficiency.  Secondly, while the windscreen doesn't provide complete wind blocking protection (which would be unsafe with a stove whose burner mounts directly on the tank), the windscreen does provide some protection which increases efficiency.  Certainly the windscreen of the Edelweiss cookset provides more protection than the windscreen that comes with a Svea 123R.  Thirdly, the "floor" of the windscreen acts as a heat reflector which increases efficiency.  Lastly, the aluminum of the windscreen conducts heat directly to the pot.

Well, the sun is now fully up (compare the light in the below photo to the light in the first photo of  trail camp) and climbing higher.

 It's time I bid farewell to Lower Bear trail camp and made my way down Bear Creek to the West Fork of the San Gabriel River.  Now that the day is in full stride, the fishermen are out in full force.

I'm now almost back to the road that runs along the south bank of the W. Fork of the San Gabriel River.

I'll spare you the boring walk along the road back to the parking lot.  I thank you for joining me on another Adventure in Stoving.

  1. Thanks for dusting off your equipment and discussing the merits of older tech. I concur. I have the Sigg version of the cookset and it can make a big pot of conventional rice when used with the better simmering 123 stove. (I solo bicycle tour and like the option of using gasoline in a pinch when Coleman fuel is not at hand.) Additionally MSR used to make a stainless replacement pan for the Sigg set.

  2. Hi, Todd,

    You're welcome. Some of the old stuff is really good stuff. The Sigg Tourist cookset is one of my favorites to this day.

    My old Hank Roberts gas stove ranks right up there with the modern gas stoves.

    Glad you enjoyed the post.

  3. Hey Jim,
    My cook set is exactly like yours, but I have the #71 stove, is the tank supposed to get hot? so hot that I can hardly touch it. I sent you a P.M through Backpackinglight but didn't know if you received it.

    I still think I need a new fuel cap gasket or a new fuel cap to get the proper pressure, just not getting that jet sound yet, I did have the jet sound at one time, but the tank was so hot it scared me so I shut it down.

    Thanks Jack

    1. Jack,

      Didn't get the message through BPL. Try again. I'll send you my regular email (which I won't do here lest I get spammified).

      Yes, the tank should get very hot. But unless the stove itself sounds like it's going bonkers, you should be fine.

      And yes, a new gasket or a new cap is just what you need if you're not getting pressure.
