Got it working for the photo shoot...
Sam: Nice Coleman 520 - great flame. I can't figure the number of legs. The Ernie Pyle has 4, my green 41' has 3 and your 42 has 4, a 43' on another site has 4 and Steve's 45' has 3. I give up. Some that are stamped Coleman have 3 or 4 legs and some that have no makers mark have 3 or 4 legs. Mike...
Steves 45 has 3 legs. I am at the same point Mike... just when I start to figure it out I find out I am out of beer.
I guess I've only ever seen '41s and '45s online. I don't think I've seen any of the other dated stoves except for my '42. Are there '42s with 3 legs????
Sam: Is your 42' a brass or steel tank? The M42' which is a different design and is the forerunner of the M1950 was consistently 3 legged as for your 42' 520 I am fairly sure I have seen 3 leggers. However right now I am seeing double. Mike...Mike...
I'm pretty sure it's steel with the rust on the bottom of it around the rim and on the out side, which can be seen in the first pic....
I don't know what my tank is made from, but a magnet won't stick...
Nice flame, very nice - who says these colemans won't last 80-100 years - with some minimal maintenance I bet it would run for another 60 years
Is there a strict correlation between 4 & 3 feet and small vs large filler hole/cap, respectively?
Thanks for the kind words Tom. Yeah, I was surprised how easily it fired up - a few pumps, light it, and after the initial warm-up of a ferocious, 18-inch, yellow flame got the nice blue flame above.
I think age of the stove has a lot to do with the filler cap size rather than the number of feet (maybe I'm wrong here). I know this one is small since the coleman funnel barely fits the opening. Later models have the larger filler cap, for example, the 530.
There were multiple manufacturers of the M1941, perhaps one or more followed their own ideas on the number of legs. The post-war 530 would be better for some stabilizing legs.
I have used an alcohol prime on the stove to reduce the dramatic, pillar of fire affect that comes with the stardard lighting procedure. Although not very visible, there is a prime cup behind the windscreen.
Paul: The prime cup is only on the later ones made with diesel/kero in mind. Take a look at the Ernie Pyle's and my 1941. I don't think the 42's had them ether. The early war 520's didn't have them. The cup and modified generator made the late war 520 a true duel fuel stove. Nether version needs a prime for gas/ Coleman fuel. The 530 also doesn't have the priming cup I believe. Mike...
The 530 doesn't have a priming cup either. Paul, your are right that the "M" stoves have a priming cup, like the M-1941 and M-1950 stoves. There are two styles of stoves. One style is seen in the 520 and 530 and the other style is the "M" stoves. All of my "M" stoves have the priming cup, while my 520 and 530 stoves have no priming cup.
Hi all: Last night I called a WW11 vet. friend that was in Patton's army. I did so because of the questions on this post and the fact that he and I have discussed the 520 in the past as he carried one. He says that he hated the priming cup but was under orders to use it at night so the enemy could not see their location. His quote was that the stove "took a week to light" if the priming cup was used. During the day they did not prime the stove. He said all the stoves he saw had priming cups. He also said it would run on diesel/kero without priming. Mike...
Just wanted to paas this link on
It's a M1941/520 on Epay. Evidently Coleman called it a 520 , while the military referred to it as a "M-1941". It has a priming cup and three legs.
It gets a little confusing sometimes when designations for these stoves can be different and then you throw in the dates involved and it all gets a little muddled.
Also on the Ebay stove there is a picture of the spare parts and it lists a "M-1942" as a two burner. Could that be what is known as the 523 ?
Pretty sure the same burner is used on both the M-1941/Coleman 520 and the two burner M-1942/Coleman 523. Is that the issue? There is also a 1 burner M-1942 stove, but I don't know if there was a civilian version ever sold.
Your right itchy. The Coleman 520 uses the same burner head as the 523. The burner head/bell the M-1942 used is very similar but not really.
Note the rectangular holes on the side to allow the folding pot supports to go through. The 520 burner head has circular holes, among other things.
The M-1942 (Mountain stove) the M-1950 (536), and the 523 are all inventions of Bestor Robinson. The 520 (M-1941), 530 and the generator was Boyd Tullis. Tullis worked for Coleman Company.
That said all these stoves share parts or something in common. The U.S. governments doing so no doubt to simplify the production.
In the orginal patent of the 520 there is no priming/preheating cup. The instruction for the one without a preheating cup are very similar to the one with it. There is no mention of filling the priming cup before lighting. Seems to be something they added to please the military indeed.
Hi all: As Jeff said above, the priming cup possibly came from military need. See my post #119810, four posts above. Mike...
"Military requirements/specs" I think is what happened. The spare parts and multi tool I believe were part of the specification too.
On another note, the way the M-1942 Mod. Mountain stove is fired up is more "normal" But again fireballs in enemy mountain territory is no good.
Sorry to go off topic.
