The P. 108, was a fantastic machine to be shure,It would be if added a Great Axis Heavy, It had no Tail gun but mounted on each wing their was a remote controll reward firing barbet, containg 2 12.7mm Breda MG's, that could easly cover the tail. Also their was a Ventral turet, and waste guns as well, the only real differance in arament (defensively) is the deferance in 12.7 mm Breda and the 50 Browning, in terms of coverage they are about equil.
O the P.108 is torpedo capable:)
Beneto's son died in one, over Geberalter I think.
Now after saying all that, I must say that, very few were made, and If I had to back an Axis Heavy it would be the He 177.
But back on to my crusade for an Italian Bomber the Cant Z. 1007 is by far the best choice:)
