The mysteries of Italian hand made craftsmanship never cease to amaze. We were inspecting the dash heating and ventilation levers and found that they all seemed to be cut with a hacksaw. Not only that all 4 levers (including the choke) were cut like this and there was no evidence that they had ever been taken apart.
Complicated explanations and justifications were all abolished with the help (again) of our friend in Germany, Matthias. He sent us photos of an NOS lever and certified that indeed, the Italians cut parts to fit on the assembly line.
I can only image the confusion in ordering a replacement part back in the day.
