This is a pretty interesting read with some nice reference pictures (scroll down 12th & 14th post)--

I think it's a bit too obscure and involved for FH2, but really a neat piece of history from a rifle collectors stand point. To sum up the article for those who like the condensed version --

The grenade attachment was activated by removing the bolt from the receiver and inserting it into the grenade assembly.

The grenade itself was more of a "stun" grenade that produced little fragmentation (idea was to launch one off prior to charging a trench in order to gain an element of surprise over the enemy)

Pre ww2 design (1928)

Extremely rare, only 14 "milsurp" examples ever documented. Royal Italian army designated it the "Tromboncino" model 28

Not all of these weapons where dismantled...would make a nice pickup kit none the less. But the Brixia 45 is more important At the moment

...and the fiat revelli 1915 MG

though it looks slightly unwielding (as in bulky), the design is pretty damn awesome, I'd say.
