What a find! Very cool topper from a first place racing trophy that was dated 1956. It makes an even cooler hood ornament or shift knob! Its a 5 spoke mag wheel with a treaded racing tire with bird like wings. Made from jewel quality silver laden pewter polished to a chrome like luster. Measures 4 3/4 inches tall. It has a 1/4 x 20 threaded brass insert for mounting, but can be cast with any size insert you want.
