The matchbox model is indicated to have a 1/42 scale But since it is usually smaller, it could pass off as a 1/43 Here is the model with some added features . You can see the difference between the stock and the modified versions.

I already made initial modifications with a repainting of the side steps , tire wheels and adding windshield based on some photos of the real thing. That was five years ago.
