To answer your questions on the guns. The 20mm was a Navy Type 99 Mk II that fired the 20x101 Rebated Rim Oerlikon cartridge. This was a disintegrating belt fed gun that had a firing rate of 480 - 500 RPM. The 30mm gun was a Navy Type 5 that fired a 30 x 122 Rebated Rim cartridge withe a disintegrating belt fed gun. We have no surviving examples of the links, or gun, so we don't know the rate of fire. Source is "Japanese Aircraft Equipment, 1940 - 1945". The contributing author that wrote the chapter on Machine Guns, Ted Bradstreet was a good friend of mine. The observer was removed and the guns were fired by the pilot for the night fighter version. Source for this is Wikipedia.
