WW2 Russian grenade ID

[MINENAZ16]

Hello,
Try to find designation and filling of this grenade ?
Diam : 80mm
Length : 215mm
Not RGU-38.

It would seem to be (though I'm probably wrong) the base grenade, without the over charge, of the RPG-41/RGD-41 developed by M.G. D'yakonova (М.Г. Дьяконова).

As mentioned in your other post.

No base grenade in heavy grenades you show
The first page of your documentation seems to mix grenades.
Herewith RGU38 but the grenade for ID is different (fitted with top screw - filling hole ?)
