The Type 97 cannon was known as the Ho-1 when used as a flexible weapon
and the Ho-3 as a fixed weapon. It was developed from the Type 97 antitank rifle,
which in turn was
derived from the Hotchkiss, and it used a combined gas plus blowback
action. The Ho-1 used a 15-round
double drum magazine while the Ho-3 used a 50-round double
drum magazine. The Ho-1 was always mounted in a complex mechanical
turret with its own recoil absorber, so the recoil absorber of the
original Type 97 antitank rifle was retained only in the Ho-3.
