Inert Russian RG 42 Fragmentation Grenade.

The RG-42 was originally introduced during World War II from 1942 onwards as an emergency measure to replace the RGD-33 grenade, a pre-war design which proved to be too complex to operate, too expensive and time-consuming to produce. It remained in use with the USSR, Warsaw Pact countries, and Communist China in the post-war period.This one is in very good condition, disarmed, inert and totally safe and legal to own, an excellent academic example.
