Certainly was a 4 cyl car , and it was a GMH show car , Leo Pruneau was responsible for the build and Joe Felice had a big hand in the concept ( as well as being responsible for GMH's motor show displays , not that he was busy enough with motorsport of course ....)
Talking with Leo about the car it also had white rubber door seals and as much as possible was white , re the wheels they were by the looks of them Dunlop wires which makes sense given Leo's involvement with Vauxhall and his contacts in England....... HB and TA torries shared the same wheel pcd as MG Midget which of couse had ....Dunlop wires.
Joe has a look on here from time to time so i'm sure he will add some more to the history ....
