Hi,
Years ago, my son was given a TC Hawken stock with a percussion barrel.
The fella noticed my son was left handed and gave him a stock he had 'modified' to be shot left handed. Stock is useless, but it has a nice TC .50 Cal 15/16 percussion barrel with an excellent bore though no lock/trigger/guard.
I was thinking, (dangerous, I know) that if a bought a TC Hawken flintlock rifle, and a spare percussion lock, I could switch back and forth when the mood struck me.
Any reason this wouldn't work?
Jim
