Curious to see a single headlight model posing as a 1956.
Does this one have the chopped tail of the prototype?
If so, it may well be the prototype being offerred for sale to a public that its creator has chosen not to enlighten as such.
Other interesting features that the two models shared included a two stroke 125 cc Ydral engine that was started by first spinning up the flywheel of its Westinghouse Gyrostarter to fulll speed and then dropping the clutch- similar to the Inter's mechanism for same.
