I got the name Graham Gant from, of all places, a certain forum of which we are both members. No names, no pack drill. A thread on that site concerns one-off specials, and mentions Stan Goldthorpe's WEV, but goes on to claim that it was one of a short series of one-offs built by the Gants, mainly Graham. So I suspect that this WEV was built by Gant, driven by Goldthorpe.
(PS it's great to have MJW back!)
