My father acquired this knife while visiting Germany with a Boy Scout troop sometime around 1937-1938. I've recently begun doing some research on it. I've looked at hundreds of pictures, but I've yet to find a hanger with the strap in this position. Were any made this way, or is it a user modification ? It is stamped L F S on the reverse, with the F in a oak leaf.
Thanks in advance for any info.
