I have a 45 TC flintlock from the late 1970s with original frizzen and old style ****. Have been told that TC only case hardened that vintage of frizzen???? This one looks like some bad road but still lights up prime very consistently. No idea how many shots through the gun. Has been shot a lot by many different shooters (it gets a lot of rides to the range and will get pulled out if someone shows interest in shooting a flintlock). Stock has been redone twice. Barrel was blue, now brown. Have a modified Lyman frizzen as a spare for it but has not been needed.
