As discussed in Derek Meddings article in Cinefex February 1990, it is thought there were three different sized scaled models made of the Batwing for use during filming, which included a 1/4 scale model which was about 10ft long for close ups and with automated parts, a 6in. model -- 1/46th scale-- for action shots and a principal 1/12 scale model such as the one in this lot, which is believed to be the one used to crash onto the Cathedral steps.
The Batwing appears in one scene in Batman, to thwart the Joker's plans to poison the whole of Gotham City during a street parade. The Joker and his Goons lure the naïve city dwellers by throwing dollar bills from their float to the awaiting crowds. Unbeknown to them, gas cylinders attached to the large colourful hotari balloons above the Joker's float begin to emit a deadly green gas. Batman who has been circling above in the Batwing, then swoops down through the narrow cityscape capturing the docking wires with electronic pincers which extend from the nose of the Batwing, enabling Batman to drag the balloons away from Gotham, much to the Joker's distress.
During this tense action sequence a 1/12th scale model is seen when the Batwing descends and targets the Joker before being shot down and crashing onto the Cathedral steps.
According to Chris Kenny this model was given to him in six pieces by Derek Meddings himself once filming had wrapped. It has since been carefully restored by the crew that originally made it.
