Just found 2 of these. Super neat collectors item. It has the following markings on it: THOMPSON 45 CAL
SUB-MACHINE GUN
FIRING PIN PROTRUSION
No 3972
On the ends are LO 044 HO 050 There is also a "H" stamped on it.
Someone also etched #977 and 43 with a circle R. The other is identical except it has a C with an arrow in it. $125ea includes shipping, be the first on your block to own one. E-mail me at philfordparts@yahoo. com
