HomeFUZES and IGNITERSUSSR

The re-useable UZRGM functioned the same as the "live" version.
Instead of a detonator with primer, this practice fuze is fitted with a much different tube, filled with a black-powder mixture.
After use, the spent charge can be replaced. This ofcourse after the mechanism being re-cocked.
Levers and grenades were recovered for this from the training field.
