A Pithead Baths Soap Dish.
Made from a galvanised iron. Size 5″ x 4″ x 2″ inches.
This is a newer version from the 1960’s to the 1980’s. They would be hung from a bracket that was on the water pipes just above the shower on and off controls. These dishes were part of a miners personal property, you would keep them in your lockers between shifts.
