Check out this very rare 19th century Spy Camera which is now being auction Bonhams in Knowle, West Midlands, on May 9. The Lancaster Ladies Watch Camera is a nickel-plated pocket watch with a hidden camera and is expected to retail for a whopping £15,000. Made by camera-makers J Lancaster & Son, there are only 4 more models!

Lionel Hughes, Bonhams' camera specialist, said: "This is a truly exceptional piece.

"A model sold at auction in 1992 for 47,500 dollars (nearly £24,000) so we have great hopes for our sale in May."
