Very Rustic Vintage Handmade Crude Metal Sailboat, Copper?

Description

This is a vintage handmade metal sailboat.  It is crudely made with jagged edges, bent metal and fairly sloppy soldering. I think the metal is copper but due to a lot of color oxidation, I'm not sure. It is 6-1/2" long and sits approximately 5-5/8" tall. Weighs 4 ozs. No marks of origin.
Because this is a very crudely made piece, it would make a good rustic decor accent. It would also make an interesting addition to a sailboat collection.
