Its a 36 Chevrolet grill. With thanks to Arkiehotrods for getting it right, I wrongfully had Plymouth in my first answer. Doc.

36 Chevy !!! Have one attached to my car out in the garage. Fender extensions indicate that the car was a 36 Standard.................. Jeff
Thanks for all of the help. I had no idea. I guess it could be for trade. I left the hood laying there...guess I should go get it !
