The shop can clean it up for you. Finding a matching sheath (of correct age) might be difficult but securing a current production one wouldn't be necessarily a bad idea if you wanted to press it back into use (more on this later).

If you want a proper write-up with a formal letter, crutchtip on here does that for a small fee. He's the guy that Randall will send you to for validation.

You'll have to send him the knife, though, nothing is going to be done via pictures other than "yeah that's pretty".

FWIW, if you're looking for a "user" knife, you won't have any problems trading this one for a current production equivalent with sheath. Lots of guys here love the older knives with a story behind them.
