| Weight of projectile, empty (without fuze and gaine): 6.14 kg. (13.5 pounds). |
| Weight of filling: 0.053 kg. (0.12 pounds). |

| Length over all (without fuze): 240.0 mm (9 7/16 inches). |

| Width of rotating band: 10.0 mm. |
| Fuzing: Medium Mk I base fuze (short delay) with red tracer. |
|
Operation and employment: This projectile was evidently developed to adapt the type 41 and type 94 guns for use a antitank weapons. |
| Weapons in which used: |
|
Type 94 mountain gun: Case, 11 9/16 inches. |
|
Type 41 mountain or regimental gun: Case, 7 1/4 inches. |

Type 90 field gun: Case, 16 11/16 inches. |

Type 38 field gun group: Case, 11 9/16 inches. |
|
Remarks: Identical projectiles, all with tracer have been found marked with either a single white band near the middle of the body or with white-and-green double band (green in conjunction with another band indicates presence of tracer). It is believed that this represents optional marking in the new system rather than old and new marking. |
