Thanks for the useful information. I have found my fuze in a 57 mm unguided practice rocket.

Does anyone have a more detailed photo of this fuze as a cutaway model? Or a photo of this fuze in disassembled condition...

greetings

Maybe someone can help me: When the rocket is fired, the sleve(8) moves down and releases the upper balls(10). When recoil forces are over, the sleve moves forward an releases the 4 safety balls (18), that hold the striker(5). How are they released?

Thanks...

After the upper balls fall into the fuze cavity the sleeve can return furter up freeing the way of the lower balls. The hole for the lower balls is not visible in the front cutaway, because it is not in-line with the cutting plane, but you can see it on the A-A view.

I have the same opinion as you.

Thanks, that makes sense. 2 balls to the right, 2 balls to the left.

2 balls to the right, 2 balls to the left.

yes, as the cocked striker forces them outwards
