In 1938 it moved to the new quarry for the Tottenhoe Lime and Stone Company Limited, Stanbridgeford, Bedfordshire where it is understood to have operated under the name of ISOBEL until quarry closure in 1965. Transferred to Barrington Cement Works and quarry in Cambridgeshire it worked on until retirement in 1971, when it left for preservation during which it gained the name BARRINGTON after its last industrial plant.
