Looking forward to what you find Marcogrifo, appreciate any effort! As I stated above, the article mentions that it was built and flown in 1945.
And I must apologize, it seems like sometimes fingers are faster than brain!

Yes a SM.95B prototype did his mayden flight in 1945

Anyway, I'm not completely wrong, because the develop (or better, the completion) of that "bomber" was a dispensation from peace treaty agreements

An excerpt from an article about SM.95 I've found on an issue of "Aerofan" magazine:
It almost looks more like a 4 engined SM.82 then the SM.95
Yes, you're right, that is precisely the look (and the essence) of that project

The profile shown in Graeme's post seems, I think, a speculation about the look the SM.95B should have had.
But these below are "the original drawings" found by the Aerofan's staff
Quite a merge between SM.82 fuselage and SM.95 wings, isn't it?
That's a great find, the Piaggio P.108 was the only 4 engined Italian bomber I was aware of.
And me too

Finally, the only two known photos of SM.95B
Cheers
