Actually I did consider that at one time, though I never carried through on it. Back when they were still around I ordered from Narragansett Armes their Early Virginia Rifle with the Chambers round faced colonial lock. For some years after that I saw many ads in Muzzle Blasts and Muzzle Loader featuring some of Chambers' locks from different periods and often thought how interesting it would be just to buy the locks as a collection of flintlocks.
