I bought one recently. This is the same lock that Ron Long used to make in the 1970's. The Hawken Shop has Long's original molds.
R. E. Davis makes a similar lock. The external parts look to me to be the same, but the internals will not exchange between the Hawken Shop and the Davis lock.
R. E. Davis bought what they thought was Ron Long's lock, triggers, and breech plug business from a Tim Houseweart, but Tim had previously sold the flintlock molds to Tom Faux. Davis asked Ron Long to make another set of molds for a flintlock, which Ron did. Tom Faux eventually sold his lock molds to the Hawken Shop.
The quality of the Hawken Shop flintlock is good. The frizzen spring that Ron Long designed is small, but seems to work ok.
