Smith & Wesson Single Shot 22 : Revolvers at GunBroker.com

Appreciate the comments. i inspected the pistol today at the dealer, but still have the wait period. It's not bad. No deep pitting. Has what may be a barb wire stringing mark on the barrel. I have seen this before on Colts of the period. I have an 1891 barrel and cylinder I may try to mount. The pistol is rough enough that it would not bother me to re-blue it. Seem to function fine too. A bit of looseness in the lockup of the barrel break. More later when i pick it up.
