I found the old Pierex (sp) wasn't too bad, tough glass. I ended up buying a lantern case form the Army&Navy so I never had a problem after that. But that shows how old my experiences were. I think the #411 Tourist stoves were a Canadian model. The Yanks had a bigger 2 burner stove #420 ???. I still use an early propane version, '74, of the #411Tourist stove for outdoor cooking with our travel trailer.
I would think about buying a garage sale stove just to get the plunger.
Going by a rather old memory, the white gas kicked out 22,000BTU and the propane only 18,000. Those " Band of Blue" burners could really boil water quickly, but could simmer so low the coffee was almost too cool. Amazing.
My compliant is how expensive white gas has gotten , errr, I mean Camping Fuel. I remember my dad buying white gas at a service station in bulk from a hand pumped 45 gallon drum .
I have an old lantern that uses a separate pump, no glass just open mantels hanging. Havent used it in over 30years as no hand pump.
I think I can help you out. I have a few leather pump cups around. Probably a washer that connects the cup to the pump shaft too. If you want to DM an address, I can post them out to you...
I think that some people make their own out of a piece of leather too.
just looked on amazon.ca there are parts including the leather ones /
Old coleman parts sells virtually everything
I toss those rubber pump washers and replace them with leather cups. I think leather cups are around 3 bucks.. the fuel cap seals are cheap as well.
I hate that coleman fuel is $50 a gallon tho. I've started converting my coleman stoves and lanterns that I use regularly over to kerosene. Cleaner , cheaper and hotter
