Check Dixie Gun Works. Lyman is a quality gun. Around 1985 there must have been 50 different pistol kits available from 12 manufacturers, now there's just a few. Traditions, CVA, & Lyman are basically the well known makers of pistol kits. I don't know what happened to Palmetto Arms, (made in Italy) I have 4 of their pistols. Three of the kits were excellent quality. One was very rough. Some Custom gun makers sell kits and semi finished guns. The Kennedy Pistol is one. I'm not sure where you can find their website, since the apprentice just took over the operation, when the owner died.
If you are very adventurous, you can select individual components from an outfit like Track or Dixie and build a custom gun. Or some semi finished or partially inlet can be had.
I put together several inexpensive kits and then started cutting my own stock blanks out of saw mill planks.
Even made a pistol using walnut from the old family farm.
A pistol stock is not real difficult. I cobbled together a clamp of angle iron so I could rout out barrel channels and even a jig so I could use a dremel router for the lock plate mortises. At this point however, you are filling up the shop with tools.
