All About Pocket Knives

Hey, selling off my late father's collection, unfortunately his records were not very good. Can anyone help me identify and value this knife?
- Only stamp says "Buck U.S.A." no model number
- 3 pin
- Just squeaks over 7" open
- Does have mild wear and tear, worst is some dimpling at base of handle in the pictures
Any help appreciated, thank you!

Should be 1972-73

This link was posted on the other forum I frequent, and could be of use here:

There are also some sweet knives shown on that page if you scroll down a ways.

It’s a nice early knife. In that condition I would think $100 tops. You’d have to find a collector that needed it.

I failed to notice that the OP knife was a 112 Still, the link I posted may be useful.
