Fish decoy

I've had this fishing decoy sitting around about forever and wondered if it looked familiar to anyone. It appears to me to be factory made with airbrushed scales and molded ribs on the front fins which are cast in lead. The mid-fins and tail are tin. The eyes are metal buttons. Overall length is 8 inches. There is a big ol' chomp on the head ~ either that or it got whacked with something. Otherwise not much usage wear. No markings at all.

That's really all I know.
