whilst looking through a copy of the English Electric Co. Ltd. war diary, I notice an entry that shows that an order for 1 million cast filling hole plugs and 1 million base plugs was placed on 25th July 1940 with the EECo. Stafford facility. The components were delivered at the rate of 50,000 per week between August 1940 and April 1941. I thought that was quite interesting and thought that someone else might too!
