All About Pocket Knives

I have an old case hunting knife I got from my dad that I am trying to found out how much it might be worth. It has been used for cleaning deer for about 30yrs now and has been sharpened twice. it is by far the best knife either one of us has ever had or used. Was just wanting to find out some more info on it if I could. It has an Indian head and Arapaho ingraved on the blade. The #'s on one side are R503 over SSP.

wilburx3, First off,welcome to the site,your gonna love this place if you like knives.Sargents 6th says that your knife was cataloged between Nov.1978 and March 1989. As far as value goes,do an e-bay search, they are still out there.You have a very nice wooden handled knife so keep guttin and skining those deer. Hope this helps,Mikek
