Full item description text is below the video. The video may not play on all platforms so I also included a YouTube video link beneath the first video file. Video will open in a new window. The sky blue enamel case is absolutely amazing and the enamel is perfect (no damage or repairs). Gorgeous hypnotic effect guilloche tooling, solid gold appliques and engravings adorn this exquisite case. The case is solid sterling silver, gold gilt and is hallmarked. This was crafted by a rather uncommon singing bird box maker, OMM, in the late 1880’s/early 1890’s. OMM helped Karl Griesbaum establish his factory in the early 1900s. The guilloche designs beneath the enamel are exceptional and the gorgeous enamel color presents differently depending upon the viewing angle and light source. The same hold trues for the iridescent nature of the hummingbird feathers. True fired enamel with expertly applied gold appliques is very rare and this case is superb in every respect. The bird is one nicest you will find on a going barrel bird box with brilliantly colored iridescen feathers (pink, red, green, blue and gold). Iridescent feathers present themselves differently depending upon the light source and viewing angle. I tried to capture the beauty of this bird using different angles in my video but cameras never do these feathers justice. The original solid brass and pinned mechanical movement is also in excellent condition and was just fully restored, including the bellows. OMM movements are different than most with a very long and rear positioned governor fan. This movement is exceptionally sturdy. In summary, this is a fantastic antique singing bird box in amazing cosmetic and mechanical condition. Buyers should be cautious when purchasing an antique singing bird box – always insist on seeing a photo of the mechanical movement for any singing bird box described as “antique”. This significantly impacts both current value and future value appreciation. The bird animates perfectly as follows: wings flap up/down, beak opens/closes, tail flutters up/down all the while singing to a beautiful oscillating bird song that is synchronized to the bird animation.
