Cast brass handbell with turned wooden handle and heavy chain/ball clapper. Approx. 25cm tall. Nice Air Ministry and King's Crown markings on the brass collar. Also marked with a 1940 contract number. Shows use and wear but in very good condition overall. The use of these was probably varied and may have included service as fire bells, calling men to order for lectures/briefings, air raid alerts or even to help 'scramble' fighters for a sortie. Stock code M16210.
