Antique Cast Iron Toy, Ro-To-Top Spinning Top

An antique Cast Iron Toy, circa late 1800s- early 1900s, a Ro-To-Top Spinning Top. The rare cast iron metal toy measures approximately 2 1/2" wide by 3 3/4" tall. The name RO-TO-TOP is embossed on one side, the other has a design on old paper. The spinning top is in good vintage display condition (I haven't had a successful spin!) with aged patina.
