Whilst the New Bond Street saleroom focuses mainly on fine art, the Knightsbridge branch of Bonhams has a broader remit

Sales are primarily aimed at the collectors' market and can contain anything from rare first editions to fine wines, suits of armour, furniture and classical sculpture.

Some of the things you can buy here are quite incredible: the only strange thing is why some people want this stuff in their own home, and why they're willing to pay quite so much for it. Antique duelling pistols anyone?
