This stove folds up into a 7 x 4.7 x 1.625 rectangle with fold down supports giving it that Mousetrap appearance. Fuel comes from a canister that connected via a half inch tube inserted into a canister. from what I understand the canister used on these had a rubber nipple and no screw connection was used. Still I cannot say if this stove has the complete under carriage but it seems to. Also, sounds like the fuel source for these is pretty tough to come by so it may be so a collectors item only anyhow.
