and is this K box ok i made it off my printer one on the left is store bought should they be lighter??
Doesn't matter.. The "C-Ration" box is a case of MCI's (Meal, Combat, Individual), the predecessor to MREs.. (and the "C-4" menu is the latest, meaning late 60's/early 70s) and made of cardboard... Wouldn't be on a WW2 tank, as the Army didn't field that ration until the mid/late 50s.. The K-rations look good, although the wood case could be discarded (or put to better use, which was what generally happened with GIs in the field) and just the paper case being loaded onto the tank.. Early K-rats were stamped with "KS" symbol
Colors could vary depending upon how many times the case got wet..
