well that would be just about right use/place for it i bet,i also have one Stag brand little multi-folder in my Adlers tool pouch.
by the way do they sell any old school tool/gear bags&pouches there,ones u can strap on frame tubings or under the seat?
here they only sell as"vintage" some plastic ones.my Adler has although a pressed paper(kind of) tool pouch,its from time after our last war when leather and everything was expensive and availeable only to some rich folk.
the thing youre about to have,doesnt require much to restor eit,its new but its been in my moving boxes so theres some minor dents etc.youll like it i know.
