Update:
I ordered RCA I, Gunsmith of Grenville County, and Thoughts on the Kentucky Rifle in its Golden Age from TOW. RCA and GGC arrived yesterday evening, and TKRGA has shipped and should be here day after tomorrow. I skimmed through RCA trying not to drool on the pages, what a great book that's going to be... and started looking at GGC, which is impressive. He goes into way more detail than either of the other two books... I can tell it is going to be the go-to book. The only disappointment is they shipped the hard-bound version instead of the one with the ringed binder that will lay flat.
I've also had e-mail communication with the Chambers', and done some more "soul-searching", and I think I've decided to take most folks advice and go with the Chambers kit for the first one. I got lucky and caught up with them because some of them had to come back early from Friendship. They answered some questions, and invited me to call back after the 20th to see what they have in stock, and set up an appointment when I can go up there and pick everything out in person and maybe even take it home with me. Very nice folks, and I look forward to meeting them and seeing the shop. Of course, I will report back afterwards.
Thanks again for all of the help and advice. Hopefully this project will be off and running soon!
