This 3 foot diameter 16 mirror chandler is something we have never seen before. We found this example in Italy and told that it originally was used for scientific experiments with light. In addition The dial on top was for changing and focusing the mirrors. That has been fixed in one position to stabilize the heavy lass mirrors. It has an amazing Steampunk Industrial look like on other. It has been restored and newly wired for standard US bulbs.
