Victorian spy camera disguised as a pocket-watch

This Victorian "pocket watch" is actually a cunningly disguised spy-camera:
The Lancaster Ladies Watch Camera was brought into Bonhams by a gentleman whose grandfather had owned it originally. He was a cabinetmaker at the Birmingham-based firm J. Lancaster & Son, probably working on the many wooden cameras sold by the company. The vendor, consigning several watches to one of Bonhams’ sales, noticed that among his collection was what looked like an ordinary nickel-plated pocket watch case when closed – but when he opened it he discovered that it actually contained a tiny camera inside.
