The Auto Ordnance company made a couple different types of cases for the Thompson SMG, and today we are going to look at two of the most common and one exceptionally cool type. The two most typically found are the Police and FBI cases. Both of these hold the gun along with the detached stock, one drum, and four box magazines. The Police type has the drum and box mags separated for balance and was lined with purple velvet; the FBI case was generally blue velvet and had all the magazines on the left (making it balance poorly).

The other case we have today is one fabricated by the Secret Service for one of its protective details. This is a flat-lying wooden case, which holds the gun, stock, and four box magazines - no drums for the Service.
