Roundhouse Farm between Fairford and Cricklade is I believe their main gravel pit, Dairy Farm quarry is the tip and concrete plant near South Cerney. I think the HQ is at Frampton on Severn.
They do spec their tippers well, I saw one of their latest CFs with a steel body and had a payload card in the window with “19” on it. They’ve got an old ERF EC unit still about, saw it last week near Cirencester.
