Hi William,
Interesting example, thanks for posting
IMO this is original type 1 zinc FO U-boat. Indeed part of the maker's mark is missing but I think that just something went wrong during the casting process. I have not seen missing cross-bar on the 'f' so far but deficient makers marks are not a rare phenomenon on FO u-boats.
Cheers,
Hubert
would not a dirty die put a mark on the badge not miss a bit out
No, debris or dirt on the reverse die would create a profile that results in a negative defect in the badge. If debris was just filling the recess of the negative f.o. mark in the reverse die, then that would cancel out the positive profile mark in the actual badge.
It's a reasonable theory, but it could also be that those bits were just sheared off in the final product.
