In order to test the Lucas LR.{Mr Ellor}7 Regulator on the first two cars, we have had two units built up on our standard moulded base and using our standard cover D.54550. These covers will require ventilating holes, as sketched below. Please add these holes when the completed units are received from Messrs. Lucas. Subsequent units will have a new base and the cover will not require any ventilation. [Diagram annotations] 1.500 PITCH .750 .500 1.500 10 HOLES (5 EACH SIDE) .500 DIA BY/RD. | ||
