Designed by the Office of Naval Research's Special Devices Center, this cutaway measures 77 inches in overall length, and demonstrates the inner workings of the Browning Model 1919A6 Machine Gun. The base bears an ID plate for the National Guard. Included with the demonstrator is a canvas ammunition belt loaded with 6 hard plastic dummy rounds.

Fine, with mild handling marks and wear overall. The model shows some scuffing and cracks. A number of chips are present on the dummy rounds. Mechanically good.
