Gun rooms to go to

QI have friends visiting from Texas this autumn who are sporting-gun mad. Every year they like to look round a gun shop they haven’t visited before. I have taken them to most – the Purdey, Holland & Holland and William Evans gun rooms, Beretta Gallery and Rigby showroom – so can you suggest anywhere else that might offer an interesting range of top-quality guns?

ATop-quality guns can be seen at Boss & Co, Richmond, Surrey (tel 020 8948 2781; bossguns.com) and Watson Bros at Tower Bridge Road, London (tel 020 7378 9700; www.watsonbrogunmakers.com). I suggest contacting both companies directly before visiting for opening times and to discuss the possibility of a tour, meeting craftsmen and discussing potential purchases.
