In a recent thread, Walter Snyder posted a couple of pictures of and order for four cases of guns going from Ithaca's Lefever Arms Company, Inc. to H & D Folsom Arms Co. in New York City on June 20, 1934. The first two cases were all Lefever Nitro Special doubles. Serial numbers ranged from 262104 which according to the serial number chronology would be 1928, to 297562 which according to the serial number chronology would be 1930. In another case there was one Lefever Single barrel with a serial number 9319 which would be 1928 and the others were in the 214xx range which would be 1931.

Just an example of how far off these serial number chronologies can be.

The one for A.H. Fox guns is worse.
