With all the parts now in hand, I headed to my workshop with the last two parts from Ebay. Both were new old stock 1917 parts, and are nice. I’ve finally figured out how to assemble and disassemble the gun, so after about 10 minutes I had the trigger and hammer groups in and things seemed to function fine. I dropped in the cylinder and put the side plate on, and said a prayer. The S&W gods were not smiling at me, as I now have a gun the works beautifully on one cylinder (#3, I marked all the positions) in both single and double action, and hit or miss with double action on the other 5 cylinders. None of the other 5 positions work single action. It appears that I have a timing issue. As the hand is one of the new parts, I’m guessing some of the notches on the ejector are worn or not being engaged properly by the hand. I’m going to try reassembling a few times with a bit of better lubricant and see if anything changes. If nothing else, I guess I can fire her single shot on the #3 position. I’m amazed by the quality of the machining of the parts in these pistols. More to come...
