Alan, if you had asked before you started, my advice would have been to not waste any time on a Crescent... unless you just wanted to practice some gunsmithing techniques before working on something more valuable. They made a ton of Crescents and Crescent Gun Co. variants, and when you see them at gun shows, most have shown they did not stand the test of time very well. Even complete guns that are still in decent condition don't sell for very much because they have no collector value.
But since you are into it, and it beats just watching TV, you could start by doing searches on Ebay every few days. It's only a matter of time before another one gets parted out and listed there. Unfortunately, there are a few purveyors of cheap worn out gun parts on Ebay lately that are selling a lot of junk with crazy-high starting bid prices. You have to sort through all that to find someone who isn't smoking crack when they list their junk. I also see a LOT of Crescent parts in boxes of gun parts at gun shows. Most aren't labeled, so you need to know exactly what you're looking for.
