1986 Kenner 25th yr Anniversary Spirograph Set Incomplete

A 1986 Kenner 25th yr Anniversary Spirograph is featured here. It is in the original box. It is mostly complete. It is missing 1 pen, and 1 propeller shape. The # 24 circle gear is bent and odd colored. I'm not sure it it got too hot? The original booklet is also included. The box does have wear from age and use. Please see pics closely as they are the best indicator of condition.
