Shigeru from Japan sent me these photos of a British Made Thompson 30-round magazine pouches. They have the fittings at the back for the British Mills belt, mounted diagonally for wearing them one on each hip. They have a British Made stamp on the back with year 1944, which I believe indicates British Made equipment for the US Army. But these could never have been used by Americans, as it would not fit their webbing. From the pictures I’d say they weren’t modified from American pouches either.
This is a very interesting set. Please comment if you can tell us more about this.
