Gong, origin unknown I received this from an acquaintance several years ago. I was told it was purchased at an antique shop and was quite expensive. I believe a gong of this thickness and diameter is rare. Diameter: Approximately 34 centimeters Thickness: Approximately 16 centimeters Please refer to the photos for other details. There are no cracks or breaks. The pitch is approximately between C#1 and D1. Thank you for viewing.
