Thanks guys, I sure appreciate all of your remarks.
These covers are of a red hew and that makes me think they are an aftermarket purchase.
The pins are peened and I think this knife is too young for that work. The book "The Knife Makers Who Went West"
by Harvey Platts puts this tang stamp at 1961.
So I'm going with recovered. Thank the Lord someone got rid of the Delrin!
This knife is hardly used. It's a fine knife and I'm glad to have it.
Thank for all the insightful input and I'm glad you all liked the knife.
