Among the items on show at Wednesday’s World Gunmakers’ Evening was a classic .410 from London manufacturer Smith & Torok.

The gun was built after the company was approached by a small calibre enthusiast and is accompanied by a unique lightweight case, covered in London-coloured oak bark leather with an interior in fine blue calfskin.It houses buffalo horn-handled tools and engraved oil bottles and drew plenty of admiration from the guests at this exclusive event
