Hi,
Ok I am some what very late on this thread.
I came across this as I have been looking for information on the Zelensky grenade and other rifle grenades of Soviet origin of the WWI and WWII period. This part of a paper/document I am writing on antitank rifles and rifle grenades of the Finnish-soviet wars.
1.
MINENAZ16 presented in his first post pictures of a Colonel Zelensky’s rifle grenade. This would appear to represent a later version of the grenade.
The original poster, another forum, indicated this had a body of cast aluminium. That poster also indicated it was a “WW1 era M1915 Russian Zielensky rifle grenade”. I am not sure if Russia had designated it as an M1915 grenade. Colonel Zelensky first presented his grenade in 1914.

Ivashkin makes a useful point in that the original Zelensky grenade had a fuse in its base. This is presented in the web documents:
English version
Domestic rifle grenades, April 9 2014
or
Russian version
Отечественные винтовочные гранаты, 9 апреля 2014

The text on these web pages indicate
Ivashkin’s version, but the sketch in the text indicates something similar to that posted by
MINENAZ16
Hope this helps.
