How many hauliers started with these old Bedfords

The first lorry my uncle drove was the MS type tipper for the NCB when they built the coke works at Fishburn County Durham his pal drove a tipper like the John Gornall one for a sand and gravel pit near Thorpe Thewels i remember as a very young boy him calling at my Grandmothers for a cup of tea ,i can not remember the name of the company that ran the Quarry ,i think the livery was grey and red (anybody?) it would be in the late 40s early 50s
