Member of a forum I frequent posted this in in the cartridge collection section. Neither he or I can figure this one out… any help?
Non-magnetic, no headstamp. The clip is not marked.
The label reads
“20 Cartriges bore 7.63 mm
Notice the misspelling of “cartriges”, and the strange use of “bore” and “mantled” - “mantel” meaning “jacket” in several north European languages…
There is also the use of . in 7.63, instead of the 7,63 I would expect to see.
