Nice finds.....the buffalo is in pretty good shape.
I found a knife almost exactly like the one you found in the same condition.
I found mine in the woods. Not sure on the age, though.
Congrats!!

Great find with the buffalo ! Got a great mickle signal on Monday night but it was a pull tab . Did get a buffalo on the beach using my sand shark on Sunday .
Your pen Knife/jack knife looks as if may be of the 1950's variety. However, they are still made. The makers name may be on the blade right next to the handle. Knife needs to be open to locate it. Like any other collectible I.D. is the name of the game. Neat finds. HHHH
