I'm researching the provenance of a 1918 Van Dorn U.S. Army M1917 6-ton Tank for an Army Motors magazine article. (There are several stills of M1917 Tanks on IMCDb.)

The tank is one of at least two that came out of MC Bradley Military Studios in Los Angeles, a company that supplied military uniforms, vehicles, and accoutrements for movie making.

If possible, I'd like to connect the Bradley M1917s to some specific films.

Can anyone help with information about MC Bradley Studios such as films, history, promotional material, etc.?

All tips and info will be gratefully acknowledged and credited.

Many thanks!
