Thank you for viewing. I'm not sure if it's brass or what metal it's made of. It's quite heavy. It has a metallic color that looks like a mix of copper and silver. The handle moves left and right. There is a "650" marking under the seat. Size: Total length (maximum): Approximately 15cm Width (maximum): Approximately 6cm I have kept this at home for many years, but I have never displayed it. I would like to sell it to someone who is interested.
