Vintage Model 23 'Gamemaster'..Rough back sheath..salmon color stone..3 thick, 2 thin spacer stack...would someone help me pin down when this RMK was born.

Rex

Here is a guesstimate! The spacers appear to be bright red vs burgandy. Based on that assumption early 1970's to 1977ish.
Is the hone stone unmarked?

Rod...
No writing on the stone...just some green tarnish where the metal in the stone pocket rubbed it.

My memory is like a sieve, but reading Sheldon's timeline the first salmon coloured stones came out about 1975 and were unmarked.
If you got the knife new from RMK, with that stone, that might help with dating the knife. If you bought the knife second hand, hone stones can be changed fairly easily.
If I was to guess about year made, I would be in the 1975-77 range. But we all know first in last out, when it comes to RMK components.
In my first post I typed the incorrect years. Bright red spacers were 72-77.

Rod..thank's for the info..I'm not the first owner but I have had it many year's..thank's for your time

Rex,
I take it the sheath is a Maurice Johnson, tight-stitched, roughback. The fact that the green verdigris from the hone pocket snap is shown and impressioned on the stone would have me to believe it is the original stone.
I cannot say, for certain, without a better look at both sides of the sheath and a close up of the blade stamp, but mid 70's is a more-than-fair date guess (as Rod has stated).
Hope this helps,
Capt. Chris

Thank you both...mid 1970's is when the RMK shop hammered this one out.
