My first 760 was a 1978 or '79 model in 30-06 & is still my favorite deer rifle. These two pumps are my latest additions. The 141 is a .35 Rem. The older 760 is a 30-06. Since taking the pic I have cut down the barrel to carbine length & replaced the scope rings with an old set from Weaver. This gun was a real mess when I bought it, the finish was about gone and there was a major problem with the rifling in the last 2 inches of the barrel so I didn't mind cutting it down. Have not fired it yet but it should make a nice short range gun.
Yes, the 141 has a 24" barrel.
