Eugene,
I cant believe I missed out Willenhall in my list of Black Country towns Many of the Willenhall lock makers of old developed round shoulders due to long hours working at their bench,locals used to refer to their condition as; "The Willenhall Crouch." As you say not much concern for health and safety in those far off days.
As I recall, Yale had a lock and lift truck manufacturing business located in Willenhall.
