This is an experiment that went bang! Instructions: 1. take two 1/2 pint Naphtha stoves (standard RM Commando Issue, very efficient, no pumps) cannot remember the type. 2. Place in steel boot-locker & cover with sandbags & mud. 3. Use thermocouple from bird incubation studies as temp monitor. 4. Regulate temp by removing 1 or both stoves. 5. Bake bread. 1st batch works OK. 6. Insert second batch. Stand well back as stoves and oven explode. Hope picture turns out OK as it is a picture of an old picture. Steve (Baker Failed)
Looks like 80's and well, I guess with the heat build up....it definitely goes "BANG", its just a badly designed oven. Not one for my books Ron
If they were RM issue they're probably No.7s, ie. 123R topworks on 80 tanks. It's not easy to tell from the pic but the 123R ribbed vapo may just be discernable on the LH stove. Also the valve spindles seem to be quite substantial on both stoves unlike the slender 80 spindles.
You got it right Ian. Just dug out the Exped Arctic reports from 1977 & 1980 and there it sez "Stove No 7", What a reliable stove it was. Just as well because we took several new stainless steel larger (basecamp type stoves) with us (under field trials) and these were supposed to have been tested from -45 to +75 Celsius. All of these cracked at the stainless welds and flamed-up. If we had not had the reliable little 1/2 pint Naphtha bombs we would have been in real trouble. I never got a reply from the MoD department that procured them. I wonder why!!!? I would love to have one now, just for old time's sake. As one of the venerable member's says "If it aint broke dont fix it" Steve.
They seem to pop up over there, now and then. Hope you can find one. Thanks, for the interesting picture and story.
