A fellow with his eYe for detail should know we weren't looking at a catalog gun
Joe old bean, even "best gun" makers tended to use standard actions. Not terribly cost effective to make one-off actions. And if pins and screws are in different places, that means a redesigned action. One with any sort of "eye for detail" would catch that--if one has some photos of Scotts to look at. And if one knows that in 1914, when this particular gun was built, Scott "cataloged" 11 different models of hammerless sidelocks. Safe to say that each one of those was not built on a different action. For example, there were 5 different quality levels of W&R sidelocks "cataloged".
