ORIGINAL POST:  I was at Josh’s when I spotted an odd device I didn’t recognize.  When I asked what it was used for, he explained it and then offered to send images of similar heaters along with a couple brochure images.  Cool stuff!

    HI Jim,

    If you can’t find a buyer here, you might try a local military museum.

    Feel free to contact me if you have any questions.

    Hi Mike,

    I think potential buyers would be curious to know if it has the hose on it (which is one of the rarer pieces)? You can see what the hose looks like in the image at the top of this post.

    Last April I donated a 796 hand crank heater with hose to the USAF Museum in Dayton, OH. It was in excellent condition.

    I’m sure those folks appreciated that Michael! It’s amazing how these keep popping up here and there.

    I have two to these heaters that I bought i a lot purchase at an auction sale. Model – 796 A-1 Serial # 5001 & 5132. One is missing the crank handle and no hoses. I talked to the follow from an aviation Museum and he said they were used by the northern bush pilots in Canada to heat the engines in the winter time. They are both in good shape.

    Hi Dave! Greetings from St Paul, Alberta! Guess what I just found on the weekend? Yep..a 796-A handcrank heater.Serial #642. I was unloading stuff at the local landfill and spotted it sitting off carefully to the side. Curiosity got the best of me and I took it home. Seems in good shape and nothing missing, but there is no hose. I haven’t tried to start it up yet. Being as we are just an hour away from Cold Lake Base, i wonder if it started out from there. Not too sure exactly what to do with it yet. Your ‘blog’ here is just about the only thing I’ve been able to find on it.

    Hi Ken,

    Congrats! I guess it shouldn’t be too strange that several of these heaters have been found in Canada (must be something about it being cold up there maybe?). It’s amazing that someone would throw a complete one away! But then, I guess there isn’t a great deal of use for them, except as museum pieces or nice touches for a restoration.

    When I looked for information about these, I couldn’t find anything either, hence the reason I keep this blog post around.

    Thanks for the note and if you have any questions, feel free to list them here or email me at

    Cleaning out my father’s shop I have found a Stewart-Warner model 796 with the hose. Clearly i have no use for it. If anyone would like to make me an offer you can email me at

    Thanks for the note Ellen. If you can’t find a buyer, you might see if a local military museum might be interested in it. Good luck!
