Not being a "T/C" kinda guy, I can't tell ya what T/C came with what lock. But yours is an old style, I can tell ya that. I do know I have one here that I picked up with an old style flintlock & plius the lock had been messed with & I sent it to T/C & asked they upgrade it. I even told them to invoice me for the repairs & was expecting to pay for such as the previous owner had messed up the frizzen spring & frizzen. They upgraded it for free, sent it back to me & it works wonderfully.
Based on what a couple of friends tell me that shoot ALLOT of T/C's, Yes, it is definately worth sending the lock in & having it done. Also I suggest ya get a new vent liner too if you don't have one of their new ones as it will make the ignition time much quicker too.
