Vtg 1971 Mattel Big Jim Enemy Zorak Action Figure

Made by Mattel, 1971. Made in Hong Kong. Zorak was released as part of the Big Jim Wolf Pack Double Trouble action figures.  Cape is missing but pants and shoes look like originals. Please ask specific questions on details, condition, and shipping prior to bidding, ITEM IS SOLD AS IS. The doll looks good but the back button does not work.  I am not sure what should happen when back panel is pushed, but nothing happens, nonetheless.  The head does not always rotate when his right arm is lifted around backwards in circles but will rotate manually. All other joints move well.
