There appears to have been four sizes of 1007 models in a very restricted range of colours
This is the largest, 1:30 scale, by Kinsmart. This model has sliding doors. Colours: Green; Blue; Red; Yellow
Next one down is a 1:43 scale, (Dinky size) by Norev. Colours: black; blue; yellow; maroon. There is also an RC version in black (see picture above)
The smallest is just 1:64 scale, again by Norev. Colours: black; green; maroon; yellow.
There is an even smaller size, called an "action model". Colours appear to be: red; green; black; blue; yellow; orange
and here are all 4 sizes
Although the three smaller sizes were mentioned in the 2005 UK catalogue, there are no part numbers. The catalogue blurb:
"Can't bear to leave your 1007 behind? Keep it with you at home or in the office with one of these irresistible, authentic, 1/43 scale collectibles in either yellow or black. Also available as 3 inch models in four colours, or action models in a choice of six colours"
