Georgian Copper Gents Pipe smokers Ashtray

Most unusual Georgian heavy copper round Gentlemans club pipesmoker's ashtray (I think !!!!). This is a beautifully made piece of early copper and is pretty heavy. Has a central cone part inside which I think is gunmetal with a turned rosewood round top part. Tinned inside. I can't think what else it could be. Very unusual and very nice.
