Some may be interested.
Brings back memories for me, my first road haulage truck was just like that, including the length, but it was only a 4 wheeler not a 6. The brakes failed on me in Herefordshire but I managed to get it to stop on the handbrake at the bottom of a hill just before some traffic lights.
The garage (Prialls?) who were fixing it said they couldn’t get the parts but then worked out that it was originally a coach chassis (hence the long rear overhang) so not a Reiver, but I can’t remember what the model name was.
Victor, Valiant or Viking, I think
All three names are familiar to me, but I can’t honestly say that mine was one of them. It was 60 years ago after all.
LAD cab four wheelers were Chieftain and Clydesdale. IIRC the Chieftain came earlier and was a 12 ton vehicle and the later Clydesdale was a 14 ton vehicle. There was a Super Clydesdale, but I think that was a 16ton vehicle with a tilt cab.
But he said it had a coach chassis, so it would be Victor, Valiant or Viking
