This one has a beautiful multi colored bird. The singing bird mechanism is in beautiful working condition, adding a touch of nostalgia and charm to any collection. Karl Griesbaum is known for creating high-quality, handmade music boxes and whistlers that are highly sought after by collectors for their unique beauty, functionality and hand made quality. The mechanism has just been fully serviced including full disassembly cleaning, lubricating and adjusting to as new functionality. The main spring has also been removed from the barrel, cleaned and lubricated. The original bellows were still in excellent working condition so I did not replace them. The mechanism works and sounds great and should provide many years of use and enjoyment. Beautiful vintage bird box. Please see my other auctions for more bird boxes and Karl Griesbaum Whistlers. Also note, included is the correct brass bird shaped winding key. This is shown in the pictures. This bird box is fully guaranteed for 6 months. If you have any issues with it at all, please let me know. Please make sure and look at the video. This bird box has great sound and great action. The bird rotates around, the wings flap, and the beak chirps. It’s really a fascinating, mechanical device to watch and see run. Please contact me with any questions. Additional pictures, videos, etc are available on request.
