This type of tail fuze is vane operated and inertia fired, and requires from 60 to 240 feet of air travel to arm, depending on launch conditions. It acts instantaneously upon impact to detonate the signal of a practice bomb.
No information about functioning.
There are no internal explosive components in this type of fuze since it serves only as a trigger for firing the signal in a practice bomb.
Nothing else to see.
