On the Side of Law and Order: The Story of Thompson Gun SN 9468

By Tom Davis, Jr.

The Thompson submachine gun is known by countless names around the world, such as the Tommy Gun, the Chopper and the Chicago Piano. Approximately two million of these weapons have been manufactured, the great majority between 1940 and 1943. The first ones, manufactured by Colt’s Patent Fire Arms Manufacturing Company in 1921 and 1922, form an exclusive family of 15,000 different members—and stories.

Serial Number 9468 is a member of that special family.

What immediately followed was the introduction of the Model 1921AC Thompson gun—with a compensator. The nomenclature of the standard Thompson gun was changed to Model 1921A. The AC nomenclature change was only noted on the AOC paperwork and not marked on the guns.

SN 9468 was removed from storage at Colt’s in 1933 and sold to the Ottawa County Sheriff’s Office in Port Clinton, Ohio, under the leadership of Sheriff D.L. Cullenen. In a letter dated March 12, 1929, a new AOC salesman named E.E. Richardson told of a business trip to the Port Clinton area to meet with local...
