This cast brass, shoulder, belt-plate is an example of the type of non-regulation accessory that was often worn with uniform. The edge is decorated with a repeating swag motif done in a combination of bright work and line engraving. The central reserve is engraved with a scroll with the 'PROSERPINE' in block letters. This is above a large foliate 'G R' which in turn is above a trophy featuring a cannon, cannon balls, anchor, trident and the British ensign. On the reverse is a hook above two studs for fastening to the shoulder belt.
