Scooterotica

i have a 60mm crank, im not 100% sure what make it is though, its in a mec box, but it needs identifying,

it came out an engine with just a bolt on pinasco kit on it.

i just want to clarify what it is before putting it up for sale

i think it might be a mazzucchelli crank shaft because i dont think the mec have the window machined out not 100% though hope this helps
