pin the cat on the curator

This jaunty kitty is a design for a stick brooch, dating from around 1860 and sketched out by a craftsman at the John Brogden jewelry firm in London. If it had ever been made, the cat was meant to be fashioned in gold while the pin was gold with colored enamel.  The Brogden firm did a lot of ancient and Renaissance-style work, so I find this a lively exception to their usual staid Victorian output.  And, as usual, I want it.  I wonder, was it ever produced?
