Jack's serial numbers are relatively close in comparison to ship dates. The last four in my database show more of a spread for ship dates with little serial number order.

The parts gun theory is reasonable and probable. First, if parts were available and orders still coming in, the factory would have assembled any number of 32-20s to satisfy orders until barrels and cylinders were gone. Only those two things differ from a 38 M&P from the 1930s, including the stocks.
The story always has been that the wood stocks were fitted to a gun frame very early in the manufacture process, so if 32-20 production stopped before 1930, all would have had 1920s stocks. Roy states in the book that the "manufacturing dates" for the 4th Change ran from 1915 to 1940, not 1930??
