Specialties of the house pull in the offbeat enthusiasts

THE way Bonhams’ (17.5% buyer's premium) empire has adapted to the received wisdom that specialisation is a key to today’s macro auction environment is to have niche markets catered for at different outposts. Among the areas catered for at the Midlands branch at Knowle are such widely known ones as mechanical music and railwayana and, in ascending degree of arcane nature, wireless sets, optical instruments, firemarks, truncheons and tipstaffs.
