One of the signature accessories of the classic "Tommy Gun", this 100-round drum magazine is marked with the model, capacity, "WIND TO 15 CLICKS" and "NO.1927" on the front and the New York address, patent dates and "NO.1927" on the rear. The second drum has the West Hurley address on the front, and is otherwise unmarked, with the interior "track" for the ammunition only making 1 full revolution of the drum.

Both drums are very fine, with some light spotting and handling marks. Neither has been test loaded.
