Just added these three nice examples of WW2 Japanese Hand Grenades:
A Type 97 hand grenade (left) ,a type 97 ceramic practice grenade (centre) & a type 4 ceramic grenade (right).
Incorrect pin on the type 97 but I have a relplica on order. Obviously the type 4 ceramic has a repro fuse assembly but the body has a nice manufacturers stamp on the base. All hard to come by in the UK so 3 nice finds and a nice trio of a collection
The correct pin. Photo source Wikipedia.
