Attached are two color photos of the port gun bay of the J7W1 at Garber. These are copyright Robert C. Mikesh, 1997. Also attached is a b/w photo of the 30-mm Type 5 aircraft machine gun at the Kentucky Military History Museum, Frankfort, KY. It is copyright T. E. Bradstreet and K. A. Huddle, 1998. Please post. This gun would have armed the J7W1, and the rusty "pipes" (ersatz guns) in the a/c photos are mounted in real mounts for this gun (the upper and lower forward mounting ears have been cut off the gun specimen). The gun is 2.07 m long and the mounting points are 0.5 m apart.
