Production cannon ball
The nickel plated brass cannon ball forms part of a production from a hat. Unusually for apparatus of this era, the inside of the cannon ball carries a metal plate telling us that it is from C. DE VERE, Manufacturer, The Magical Repository, 295 Strand, London. De Vere had his shop at this address at some point in the 1870s. Although De Vere supplied the cannon ball, it may well have been manufactured by another company.
