It looks almost like a furniture coaster -those glass things they used to make to put under furniture legs so they wouldn't mar the floor.
Somehow I doubt they would put that much work into a furniture coaster. Could it be a pin dish?
The twists are very neat like Perthshire. The canes look like they could be early P or Strathearn. Not positive on that. Maybe it is something one of the workers made as a gift for someone
