A very nice 37 pattern MkIII basic pouch for Sten/Bren mags etc. comes with the quick release buckle and drainage hole which was introduced during late WW2. This example is in superb condition, looks unissued. Just stamped MKIII and has no manufacturer stamps or date. Has what looks like to be an inverted T stamped in it? Could be late or post war, without a date cannot say. Wouldn’t look out of place in a wartime/post war collection.
