I don’t recall the queen wearing overalls, but I do recall her driving a truck, and they wouldn’t have been out of place there. Likewise cerakote on my double serves the same function as overalls on a truck driver. My double is not particularly valuable, was in poor finish, and made by a largely unknown maker, but it is for me a shootable English double at a price point I could afford and being refinished to a protective finish that is pleasing to its owner.
Just a gentle reminder that this thread asked a metallurgical question not a style one.
