Type 88 Small Instantaneous Fuze. This fuze is made specifically for the 50mm Grenade Discharger ("Knee Mortar")A centrifugally armed fuze with an internal set-back safety. When fired, the internal arming collar is cycled down and up freeing a set of detent wedge blocks. The projectile's centrifugal force, pushes those blocks out of the path of the firing pin. On impact the plunger/pin is forced into the primer, detonating the booster. Upon firing, the arming collar drops and the wedges are pushed out by centrifugal force, clearing the path for the striker. |
The text on the label is read right to left. Loosely translated the top row : "Model 88, Small, Impact Detonating Fuze". The last line is most likely the manufacturer's info... Arsenal, Inspector's stamp, etc. |
