Technically yes but seeing that nail nick won't tell you the age and that matters.
Basically from '85-'99 or so Bucks slipjoint blades were at their best and that's what I'd suggest looking for, so the tang stamps should be payed attention to.
The grind profile was the best, F&F on the blades was the best, edge grinds were the best out of the box, they were just best then.
Basically the best thing to do is just stick to the standard 300 series .
The 301 302 303 305 & 309
BTW there's also the 700 series knives to keep in mind, they have the most Buck identity when it comes to slipjoints and were the 1st Buck slipjoints made in house. The primary blade grinds are angled for some reason and it's a different kind of look but they're very well made.
The 300 series knives are great, but so are the 700 series and they are uniquely Buck.
That would be the 701 Bronco, 703 colt, 704 Maverick, 705 pony, & 709 yearling.
If you want a more conventional stockman with a serpentine frame get a 301 or 303, but if you want a stockman that's made by Buck and is also undeniably Buck get a 701 or 703.
