Let me introduce you to my little friend! I got this two weeks ago as a gift from my Marine Corps buddies. I have never been at a loss for words, but I was that day. What does one say to gift of such magnitude except Thank You and accept it gracefully. I was, and still am, very humbled by this act of friendship. It is a 1927A1 Thompson semi auto carbine made by the Auto Ordinance Corp. Here are some pictures:
Here it is in the Tommy Gun or Chicago Typewriter configuration with the 50rd drum

Here it is configured in the 1944 adaptation with the 20rd stick mag. The Marines used this weapon effectively in the island hopping campaign during WWII.
