Wheel idenitification
 

I bought a set of wheels for my 748 and are going to get them powdercoated.

But looking at them, the hubs are not like any i have seen before. Anyone know what these are from originally?

Whoops sorry about the large photos

The rear one is the same as the one I sold Sarah Jordan a year or so ago for her race bike, but couldn't tell you where it originated from

Its not the same wheel is it?:D

Someone mentioned to me that it might have been machined like that in a garage but it looks to be original to me.

It does seem to be especially light whatever its origins.
