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.

• .22 Cal. Thompsons:  Model 1928 Full Auto, and Model 1927A3 Semi Auto.

• Model 1927A1 Semi-Auto Thompson.

• Model M1 Semi-Auto Thompson.

• Model 1927A5 Semi Auto Thompson Pistol.

• Model 1928, and Model M1 Full Auto Thompson
