Later version of the single sided 15s, the 462 has 3 slight differences; the central axle is made from three components rather than one piece, the top surface of the end plate has a flat spot & the dust caps have the name Lyotard straight across rather than around in a circle.

The Lyotard 462 was first mentioned in a Claud Butler catalogue in 1967 and clearly shown on the Electron Super five. The 15s was still listed in the 1968 on the Super European but wasn’t mentioned again after this year

This pair are from my sons 1969 Claud Butler Electron super five and are original to the bike according to the previous (first) owner. they were quite badly coroded, so I only had them dip-stripped then re-chromed without polishing.
