27th October 2022 | administrator The Hillsyde Foundry of Newcastle-under-Lyme won a contract to cast Type A (large) pillar boxes in 1991, the first time they had received work from Royal Mail. Their boxes are distinguished by having the maker’s name cast onto the red body of the box, at the rear, rather than on the black base. Their boxes are also dated, with dates from 1991 to 1995 (except 1994) known.
