I owe a great debt to Bruce Dowell for allowing me access to his research into Wolverhampton Sunbeam production numbers. The production numbers I quote up until the Wolverhampton plant closed down in 1935 are the result of his research. Note that these figures are only approximate as few factory records survive. Bruce's website can be found at sunbeamregister.com.
