I think I speak for most everyone when I say- come back with pics.
One slight deviation from the Coleman theme is I have a propane lantern that is, I think, Primus. I've tried to find some details. I believe it's marked 1977. Thing is, I can't find another even close to it. The lantern head sits on a propane tank of about 10lb size, and has a neck about two feet long. The tank is marked DOT, but I think that only related to transporting.
And where are your pics???
