Just finished some research on the frame screw that SSPierce8 brought up. It looks like it shows up on the frame in the later serial numbers. Which also supports that the frame has been re-numbered. I also can comment further about the stamps if there is interest but I think the restorer was obviously trying to attempt to make an older 1st model frame look like an earlier frame for some reason? Just my opinion but it fits.

Other Americans that I looked at all had assembly numbers often 3 on the back of the cylinder. These numbers should match other numbers found under the grips and I'm really not sure on these but somewhere on the barrel and possibly on the latch? but it should be in multiple locations. Perhaps SSPierce8 can provide what assembly numbers he see's on his excellent early model? It's an excellent comparative since it is very close in serial number range.
