This cyl & head came with the lot of Vespa parts which I acquired. Almost all of these parts are for the Bravo / Ciao / Grande series - but these items are still a mystery.
Cyl bore is 38.2mm / pin is 12mm. The mounting holes between the head & cyl line up, but now I'm not sure that they're a pair.
Any idea where these belong? I need to ID them so they can be sold.
