Re the Sprints AOC960C and GMR4D there seem to be a lot of detail differences to be the same car. The front indicators, grille, number plate position, bonnet bulge, front badge, different tyres, and maybe the roof panel (but perhaps the ribs have been airbrushed out?) Also the headlamps look more level on AOC?
What would Neville know????!!
Also I was lucky enough to talk with Rob Walker when I was in the UK in 87 - he said the Traveller had a Collotti gearbox. I think he said it removed before his son took the car to Aus with him - I thought he said it went to Darwin? He wrote about the car in his column in Road and Track - I have the article somehwere.
I had heard a couple of years ago it had survived as just a shell - but it looks quite complete in that photo. There was another Sprint that went to Oz in the 60's - a new Stewart and Arden one that was on display in a Sydney Morris dealers showroom for a few months apparently.
