Another Q capt. I think I remember seeing a RMK with an inscription plate back in about 1966 at Ft. Bragg, but only the model 14. Approximately when did this option become available and did other models offer this option?

I've been looking at a lot of old Randalls lately (kinda becomes a habit doesn't it?), but the plate doesn't seem to have been that popular. Can you still get a knife with this plate?
