I have looked at both kits on the net. TOTW buys their stocks from someone, I would not doubt if it is Pecatonioca. They use the same locks and probably the same hardware, The only real difference that I can see is Pec. uses a Getz barrel ($761.50)and TOTW uses a Colerain barrel ($811.64), and the $50.15 difference...But I'm sure you have checked all this out....They appear to be identical kits otherwise....Ed
P.S Don Stith used to carry aan 1803 kit.
