Vintage Wind Up AHI Super Monsters Little Walkers Godzilla King Kong Creature

This was an original store display box that was for those ahi type windup sparking monsters from the 70's, Godzilla, King Kong and Creature from the Black Lagoon. This is an original display box and not a repro. The display box comes with 6 monsters. 2 king kong, 3 creature from the black lagoon, and 1 Godzilla. Not sure which company made these but they are all marked made in Hong Kong on their feet. All windups work except Godzilla, he no longer winds up(Overwound, maybe oil to release?) He also has a small foot tab broken off. Some walk and spark better than others so they are being sold as is. Bottom of box has small writing on it which can be seen in 5th photo. There is still more room in the box for others so if you have these walking monsters already fill the box up more, would look great. A must for that monster room collector. Thanks
