This is a M40 chinstrap I picked up on the loose. It is same dimensions as my 1950 LMZ example only lighter or khaki in color. 20 mm wide and so on. Is there a definitive way to tell on the web type? Is this a pointless inquiry and am I out of touch with reality? The weave is tighter and material is heavier than the 1950 example. I really don't know. I am sure there are endless variations in dye lots and thread count in the weave as long as it meets the specification like any military contract.
