Great historical detective work Wally and some fine photography Capt. Chris! Nice work on the enlargement Ron.
The numbers on the reverse of the sheath certainly look hand worked (inscribed?) as opposed to stamped.
As I am not particularly familiar with vintage RMKs, or Johnson roughback sheaths, please permit me to ask some questions.
-What is the approximate/estimated creation date of this knife? 1950s?
-Do other Johnson roughback sheaths from that era have model and length numbers stamped on the reverse?
-If so, are they stamped in the same location as on this sheath (in the "butterfly" as per the Capt.)?
-If so, do the numbers have a similar look or do they have more of a 'stamped' appearance?
