Think I've cracked it.
The car was featured in Oct 1968 Hotcar magazine (I was still at school!) so have found a copy on ebay. Car was on the front cover.
I saw the car in the metal in Tony's garage way back, about 2009, around his death.
Not sure what happened after that, I know Barrie Wizzo Williams went to sort the garage out after Tony's passing.
Barry was a good friend of Pat and Tony.
