First Anson and Deeley Patent Westley Richards' Boxlock 12 bore shotgun

I have just discovered that this is the first Westley Richards' boxlock ('hammerless') 12 bore shotgun ever made (for John Deeley),under Patent No 1756 of 1875, granted to William Anson and John Deeley, of Westley Richards; and gun number 5056 is engraved on the underside to commemorate that fact. It was sold at Bonhams in December 2010 for £7,800 which, for such an important part of gunmaking history, seems very little: let's hope that the new owner is a damned fine shot; has it serviced and takes it out, in due course, downing a couple of woodcock with a right and left and earns his Woodcock Club Tie, 137 years on.
