RARE 1800'S ANTIQUE TABLE ACOUSTIC ERNST CHLADNI INSTRUMENT SCIENTIFIC KOENIG

Description

Up for your consideration is an original Chladi Resonance Device. I have done some research, yet am unable to determine the exact year or manufacturer. I believe it was constructed in France, yet may also have been made in Germany, Switzerland or Austria. Based upon other examples I have found, the latest this was made is most likely 1888, yet possibly much earlier. It still works very well when sand is placed on the plates and activated with a bow. It measures 23.5 inches in length, 14.5 inches in height, and 7.75 inches in depth. There are a few small cracks/imperfections which do not compromise the integrity of this item. At some point, someone made a modification to bottom of one of the feet, most likely for proper leveling. This small added piece may be easily removed. The screw attached to the round plate is missing a couple of threads. Therefore, placing a small rubber gasket or rubber band levels this plate, and of course, a replacement screw would solve this minor issue.
If anyone should have additional information on the year, manufacturer or artist, that would be most welcome. Insured shipping within the Continental United States is $ 55.00. Overseas or International shipping to be determined at auction end. Due to the vintage nature of this item, all sales are final.
Thank you, and happy bidding  : )
