When I get my wheellock I'll let you know . I badly want one, but so far the only two places I know selling decent ones are a guy in Poland who makes one a day it seems (but wants upwards of $900 for one) and Loyalist Arms in Canada. Loyalist want $650 I think and my understanding is theirs are chain driven, as period ones were, and this is what you want in a wheellock. I am planning to get one at some point. If you want a snaphaunce, John Buck makes a nice Scottish snaphaunce, but be prepared to wait about a year and half for it
