BELL No. 59A

Used extensively as an extension bell for internal use only. Early versions came with a black Bakelite cover (see picture below) whilst later versions would have a plastic cover coloured in elephant grey, ivory or black.
Picture to the right shows a black plastic covered bellset. The paper
bag contained three round headed screws for fitting the bell to a wall.
