"I came to set straight the terms that were miss marked to the Thompson SMG.
First of all, This is the first time I've EVER heard the Thompson known as the Chicago typewriter,
I was of the impression it was known as the " Chicago Piano ", Tommy Gun "
one Glaring mistake, the M1A1 Thompson, The Real Steel SMG, Did not allow for a drum magazine to be used, just the long stick magazines
Here's an Idea, get the M1921 Thompson with the vertical foregrip, Remove it, then Attach a Horizontal forestock from an M1A1 and there you have it, the M1928 Thompson SMG, that was the last Thompson model to accept the Drum Mag, other than the M1.
I rate the cyma M1A1 an accurate looking Thompson SMG, w/o the drum mag
