Okay while I follow your thought process with regards to #5, we cannot logically come to the same conclusion with a 3-digit serial number. Again, when S&W was making the 469 pistol in the A-serial range... they were also making ALL the other semiauto pistols in their lineup concurrently. So in addition to the 41 and 52, you have the debut of the 2nd Gen full size, that’s three more pistols and all were made in the A800xxx series of serial numbers.

Cannot logically conclude that if “A800652” (made up for discussion) on a Model 469 was the 652nd Model 469 they produced. Can only conclude that it was the 652nd semiauto pistol that S&W forged a frame for after the first A800000 serial number across five different models. Seven models if the 469 and 669 were made concurrently with the full size guns and the 41/52.
