Weapons in which used:

Type 41 mountain gun (regimental gun): Case, 7 1/4 inches.

Type 38 field gun group: Case, 11 9/16 inches.

Remarks: The body of this projectile was designed for use as a shrapnel projectile em-ploying a large combination fuze. In the converted form, the projectile is filled with TNT instead of the shrapnel filling of lead balls, and a large ogival adapter permits the use of standard point-detonating fuzes and a standard H.E. booster.

Distinctive marking for this projectile is attained by painting the large adapter white.
