While doing the Thompson display over the last year or so, I was fortunate to meet several interesting people. One such person was Frank Iannamico, who wrote a great article for Machine Gun News (Vol. 10  No. 4, Oct 96) on the West Hurley Model of 1928 Thompsons. He was kind enough to provide me with copies of his research. Later, at the NRA show in Philadelphia, we were introduced to the nice people running Auto-Ordnance West Hurley, and with their help the following information is submitted.
