What type is this?-Grenade

Friend has this, I cannot find it. It has a pull ring and a striker assembly, Any ideas?

This is an Italian grenade from WWI.
Have to look for the designation. Will look it up in the coming days if no one will be faster.

Ok, caught by chance a friend who is a designated WWI specialist:

It is a: “Petardo Offensivo” (hence the “PO”)

Here’s a little more info on it: talpo.it/petardo-offensivo-p.o…html

It originally displayed in Italian, but there’s an English option “button” at the top of the page.

As for the grenade, my humble opinion is, it’s a fairly rare collectable in very good condition. An excellent specimen.

Just found this on BOCN: bocn.co.uk/vbforum/threads/8 … ID-grenade

Yes, and it is exactly the same grenade shown on BOCN and it got identified there before.

I thought it looked familiar.

A member of my club just bought it. Where was it shown before?
