It looks to be that a young boy, perhaps about 12 or 13, had a well stocked parts box and wanted a 1/25 scale Batmobile when the TV show went on air in '66, but all of the kit manufactures were asleep at the wheel. You can see where it had fins at one time, and I'd bet it had some kind of front windscreens at one time too. I guess he couldn't wait 40 years.
