All of these training grenades which I have seen have been marked RR ( first R reversed ) + number and then the handle should have same marking. Otherwise this looks quite good, does the pot have same marking as handle?
The threaded connector on handle of training grenade is made of thicker metal than ordinary M24.
No markings on the Pot that are readable...
Has a WaA65 on it and a swastika stamped just to the right of the 41brb
