Guys - being that we are all one big happy family, I want to give you all first shot at my Lyman percussion lock. Lock is in great shape. The only 'flaw' is that the hammer was professionally bent to allow scope clearance. (but you can always get a new hammer or have it re-straightened).
I got it and thought it was a T/C lock. I installed it on my Lyman Great Plains flinter to check fit and it fits perfectly. I'm only asking $25 + shipping.
