Dan, don't take it off it says "speed" all over it. It's funny what eras did to customize cars. My Dad did a ground up restoration on his '33 Nash Ambassador - only one on record left of 742 built. Twin ignition, automatic chassis oiler, safety glass, worm gear rear axle - all kinds of innovative mechanics in its day. It has the "Flying Lady", holding her breasts, ornament on the radiator cap. It was the accessory of the time.
