This is an early mid-1860's production S&W 1 1/2, 1st Issue revolver in .32 rimfire. Produced from 1865-1868. Serial number is in the 20,000 range. Overall condition is NRA Antique Fine with approximately 90% bright original blue on the frame with a bit of freckling. Cylinder looks the same as frame with lots of strong finish only its mixed with more patina to about 60% bright blue. Barrel has mostly flaked (its our theory that heat generated from repeating firing often caused finish to flake from S&W barrels) down to 30% original blue. Excellent rosewood grips retain 90% original varnish. Nice S&W barrel address with 1859 and 1865 patent dates. Action works quite well. The barrel hinge is solid with no cracks but a little bit to wear there is some slight wiggle to the barrel against the frame which is typical of most No. 1's, 2's, and 1 1/2's with the early tip-up barrels.. Bore is still somewhat bright with strong rifling mixed with typical light pits from 19th century black powder ammunition. All in all, a nice early S&W tip up revolver that is well above average.
