Yes, I think it's a good example for a couple of things, the sheath has a west facing stamp, good lord knows I don't want to create a controversy, but with the center snap it's safe (?) to say, earlier than east facing stamps and side placed retaining snaps. SGM (ret) Rodden told me he ordered and received the knife in 1964. It could have been in this type sheath, a known Johnson brown button, or a baby dot, all would be "correct". Anyway, it's great to solidify information by getting it from the horses (or original owners) mouth!
