Pair of singing bird pistols handcrafted by Frères Rochat, 1820.
Handcrafted by Frères Rochat, a Swiss watch maker who specialized in creating clockwork automatons who worked out of Geneva. Each of the pistols are encrusted with diamonds and other precious gems and inlaid in gold, silver, and platinum. Utilizing a complex clockwork mechanism, the user wound it with a key and cocked the hammers. When the trigger is pulled a bird popped out of the muzzle, dancing, singing, and flapping its wings until the mechanism powered down.
Only four other examples of singing bird pistols are known to exist, and these are the only matching pair in the world. The pistols were put up for auction by Christies, Hong Kong, on May 30th, 2011. A fierce bidding war developed between two passionate collectors, lasting for over ten minutes. When the smoke cleared, the pistols were sold for $5.8 million.
