Model 60-10, product code 102430. Adj sight, full underlug 3" bbl. (Same in 2-1/8 bbl is the mod 60-9.) Floating, frame-mounted firing pin with flat face hammer, 24.5 oz weight, standard with synthetic stocks.
I've always thought this model would make a primo trail gun-- compact, pretty concealable. Handles a variety of loads, from bird shot to light target to +P .38, with (barely) enough weight to handle full .357 loads. Not BIG bear defense, but pretty good for most other types of defense, and an excellent foraging piece.
If I didn't already have that particular niche filled, I'd follow Coltdriver's advice, and try to deal on it.
Good luck to you.
