In my continual quest for cool ducati parts, i got a really nice racing tank, the ex owner told me that it was from the racing department...
So i got curious and tried to find which bike this tank belong to, from my (quick) research, it match visually quite well the Desmo parallel twin from 1958, all the other tanks look slightly off, but the desmo twin has the same profile, tabs and cap location.
Here is the picture of the desmo twin from ducati website (could not find other pictures) :

Here is a quickly made overlay picture with the tank:

What do you guys think? anyone know of any other bike using this kind of tank?

it doesn't smell gas at all, but it looks like it did get some action at one point!

Thanks
