This offensive grenade was produced between WW1 and WW2 and was inspired by the French OF of 1916.
It has a slightly different bodyform and the M35 had no protruding threaded neck like the OF. The fuze was screwed directly onto the body.
Produced at Vojno tehnični zavod Kragujevac (War Technical Institute Kragujevac).
