Found a Case Stockman in carbon alongside the road today when I stopped to checked how my load was riding. Will post pictures when I get it cleaned up. I have never really had many case knives other than the Sodbuster and I am not familiar with the numbering system. It has a five digit number on the sheepsfoot blade 62032 is there any way of determing the age by this number? It has a jigged bone handle and squared off bolsters. BTW how do you remove tar from bone without damage?
