* Since the type 94 antitank, type 98 tank, and type 100 tank guns use the same cart-ridge case, cases will be found marked for individual guns or for all three guns. |
|
** The cases for the type 97 and type 1 antitank guns can be distinguished by the fact that the type 97 is almost straight, whereas the type 1 has a pronounced neck. The type 1 tank and type 1 antitank guns use the same case. |
