The factory was an icon. I can remember it from the 1960s and Cotswold Aeroclub Days. A parachutist landed on the roof once, didn't go through and slid gracefully to the ground, unfortunately sustaining some broken bones.
Their headquarters used to be at Arle Court on the Gloucester Road out of Cheltenham at Hatherley but don't know if they still own them.
They used to supply a lot of mining equipment to the NCB.
