The only trademark side etches I have seen are "KIT" for the old kit knives.....and the maker initials for the authorized "out of shop finishers like Leschhorn. I don't have any experience with an etch like the one in the pictures..... sorry.

You don't see many bowies with 7 spacers, usually they were 5 spacers in the 50-'s and 60's.

Never say never, but I agree with Buck..... not a shop etch.
