The Car

This version is identical to the standard 1973 version except for a purple canopy (or windshield) and 1976 style whizzwheels.

1976-79 Corgi Batmobile - now made with 12 spoke whizzwheels, Robin very small, no instruction envelope, available in blue, white and purple glass. The other main change was to the bottom of the Batmobile, which now had National Periodicals on the bottom. All versions before this just had Batmobile on the bottom. There are versions of this car that had Batmobile on the bottom, and they happened with the white and purple glass. Which were the first to have the new styled wheels... When the blue glass later followed, it had National Periodical on it.

From 76, they had national periodical on the bottom, instead of Batmobile. Some 76 whizzwheels do still have the word Batmobile on instead of national periodical, and this occurs mainly with the white glass and purple glass. Corgi had spare bins around that they used the parts of when they had run out, this is why this mistake occurred for a few hundred Batmobiles Batmobiles, with different windshields, occurred because of a mistake in the dye. Purple was too much dye, white they simply forgot to put dye in. This error occurred just twice, in 1975. Once with the purple, once with the white. They had literally thousands of them so had to run with them. This stopped in 77, when they had used up all of the purple and white glass and then went back to using the blue. Normally, this fault would have been rejected, but there were simply too many of them to chuck away. They ran with them simply because of cost cutting. which is why the Batmobile changed so much over the years.

From 1976 though, no instructions or badge were included with the car, you had to make do with a diagram on the back of the box instead!!! Cost cutting by Corgi!!
