I'm looking at an old Smith. It sais on the barrel '32 LONG CTG', and the barrel looks to be 4". On the yoke, the numbers '9642'. On the butt, cylinder and under the barrel are the numbers '241131'. It has 4 screws that I can see on the side plate and possibly another one under the grips. It's nickel. It also appears to be shaped like a round-butt. But, overall, the revo is on the small-side. Nowhere near as big as, say a K-frame. Any ideas as to what it is? Is this an old 32 Hand Ejector?
