A multi-purpose training device, this "gun" is effectively a camera mounted in an oversized housing, suitable for installation in a wing mount or waist-gun emplacement. When the trigger is pulled, the camera runs, with footage being taken of what the gun is aimed at, as well as an optional stopwatch; after landing, the film can be analyzed by the trainers for proper lead and burst timing. Measuring 29 inches overall with a matte black finish, a transparent housing and reflector array on the "barrel" for the stopwatch, mounting positions for a set of anti-aircraft sights (included), and nomenclature plates on top and on the right side behind the crank. With a hardwood transport case, with two trigger assemblies (one for wing mount, the other with a pistol grip), five film canisters, a frame for winding and unwinding the film, remote actuation cables, assorted Japanese documents (untranslated) and a 1946 dated U.S. pamphlet titled "Going back to civilian life".

Very fine, with 85% of the original matte finish, showing some mild chips and scuffs. The stopwatch is absent. The mechanism has not been tested, and the contents of the film canisters not inspected. The documents range from poor to very good in condition, with some being loose papers with frayed edges. The case is good, with mild wear.
