The lock on the left is a Chambers Ketland. But since he doesn't have a LH version, I decided to go with the Gunmakers lock. I agree, it would be nice to have more belly in the hammer & the dif. frizzen & of course the spring with roller change. However, when I build & sell the rifle with this lock on it & if the guy needs a part, no problem. If I make everything up on the lock & he breaks a part 5 years from now, he will have problem getting parts as it is a oddball lock. With the Gunmakers LH lock, ANY LH Siler part will fit it except the lockplate.
Would be nice to make it totally PC/HC. But on that thought, how many original LH Tenn. rifles ya seen ? And how many original LH Southern rifles ya seen ? So basically no matter what LH lock you put on it, it won't be PC or HC.
