Questions to the cognoscenti. These three lockmakers from Wolverhampton, are regarded being the top ones during the heyday of the English sport shotgun era. They worked for the trade. There is any record on whether any of them did excel or had a preference for a particular type of lockwork? Were their lockplates so different in their internal arragements (even those with the same amount of pins) that could be recognized from outside in the way the lock pins were distributed over the plate? Did they issued their own patents? The most important gunmakers, had they a noticiable preference for any one of these lockmakers or for a particular type of lockplate they made? There is any publication or author that did address this issue? EJSXS
