I agree with Steve.
I've also contacted the owner but he replyed me with this incomplete engine number:100418....?
Some points under your eyes:
seat cover;
exhaust sistem;
front brake disk, not completely black painted in the rivets zone;
fuel tank mole, lete repro type used also by us;
head cover engine gasket;
tires;
front and rear hub polished;
carbs sandblasted, they have lost the luminescent patina of the alloy,
upper oil line brake marked 1976;
new gauges, but appears with difficult by photos that they have the sandy drive gear;
new master cilynder and handle electric knob.
Surely i can wrong, but i'm thinking at a GREAT JOB of Vic World.
Stored, Restored by the Owner or by V.W., sincerely, this is a very nice bike and i hope the owner will do a lot of money, well for him and for us.
The new owner is welcome.
Riccardo
Your Italian friend.
