Last complete one sold 1999 for hammer price £25,000; then add tax and fees, about another quarter of the hammer price. (Just seen Huw’s post; didn’t see that one, but I don’t follow auctions closely.)
A butchered lock, with the mechanism removed and replaced with a Bramah mechanism, sold more recently, from memory c£5K.
They were probably made during a period of years. Wilkes’ workshop was also producing several other beautiful steel-and-brass locks, hinges, and other door furniture. Several others of his products are in the V&A. Rich Royalists were now safe to rebuild/extend their houses and show their royalist sympathies after 1688. Also, production of good brass in Britain increaxsed about that time, and sand-casting techniques were also improving.
