My father also worked at Reds and I remember him been very friendly with Phillip Harris who as a young man drove a wagon for Bithells of the Junction .Phillip Harris started of with to 2.no. Dodges which were bought from Pumphery ? of Flint and started working out of Penmaenmawr Quarry ,he later became a very large haulage company .
As for the Commer wagon it was originally based on the Avenger coach body with a 37hp petrol engine before evolving to the diesel version , the TS3 engine was a two stroke engine with opposed pistons it had serious braking problems and gearbox trouble I don't remember how they resolved the problems . One of the earliest operators in this area was a company from Caernarfon C.C.Williams Fruit Wholesalers I think they used to go through a gearbox every week going up the old Aston Hill out of Queensferry ,the reason if I remember correctly had something to do with the torque of the engine .
Unfortunately I have no photos of any of the haulage contractors vehicle's , but I remember seeing one of Bithells Trucks taken opposite the old cattle mart in Conwy will try to locate a copy and post it on the Forum .
Bri . your Uncle Dai worked at Bithells I wonder if his sons have any photos
