How many buttons are on the collar closer (flap)?
Large or small tag? (I can see it's removed)
Any inner buttons ? (For liners)
I assume there is no Mfg. tag in the left pocket.
all I have is the pictures you see. I spotted it earlier and have been doing a little research of my own but can find no other example of collars stitched in this way on an M43. You get a better impression of the rows of stitching I refer to on the bottom pic.
I see what you mean now, indeed, a first for me as well.
Could be a field custom applied by U.S.M.C., they tend to like modifying.
I have one U.S.M.C. custom modified M-43 in my collection, extra threads were added, made into a smaller size.
I suppose this could just be one makers variant
