Austin 7 Countryman
Comparing it with the Corgi mini, some of the proportions are different, but they appear to be the same scale. The doors are exactly the same length, but the windows are taller on the Corgi, making the Dinky look smaller and squat by comparison.
This is one of those interesting models which can be found in a range of finishes which significantly affect the value. Most of the cars you will see are light blue or grey/blue with the wood trim picked out in brown. These can have a matt or gloss finished baseplate. Seats are usually red, sometimes yellow and very scarce - light blue. You will also sometimes see it in green with brown woodwork. There are also a few examples around in fluorescent pink or orange, these have to be boxed to get full value and the box has to have a label pointing out the colour variation.
Blue with red seats is the most common, but it's a popular model and always will be pretty well priced, of these look for yellow seats, worth more again if the base is gloss rather than matt black and most valuable of the blue cars - blue seats. The green cars and the fluorescent cars will demand a high price too.
