cheers Leyland 600 ,your correct they did ,I still have my robsons spotters list and yes most were double H ,prefix and was BAO a common one also
spent many hours in robsons vehicles as a friends dad used to drive for them and would take us both with him during school holidays or sat mornings on short trips ,
all day sunday was spent washing cleaning and polishing which ever motor he was allocated or just sitting in the cab dreaming of the day we both would be old enough to drive a robsons motor on our own .
great times and put us in good stead for when we got ton actually do the job ,learning from an early age how to rope and sheet ,find your way around, fill in log books, and where the best breakfast stops were.
wouldnt change it for a second , cheers Leyland ,paul
