Hey everyone, there's a Remington RH-134 UMC knife that I'm potentially interested in buying -- I know the woman I'd be getting it from, it was her father's that he used in 1931 when he lived in Alaska, so it's at least that old -- and it appears to have (from searching on this forum) verdigris on the hilt. (And yes, she's been storing it in the sheath.) I'm trying to figure out if this is a deal breaker. I read through the forum, and know, understandably, that there are concerns about cleaning old knives. Can/should this be cleaned, would it be very difficult, would it ruin the value? I don't plan on reselling it, but some day who knows. Thanks.
