A wonderful car. The Riley was in the first group of cars issued in 1956 and to my mind the best. It is a superbly designed car and the model reflects this well.
The red model is generally the normal 205 so this is a particularly rare find to have a red one with a working Mechanical motor. The paint on this one is good with a small number of small chips. The silver work is very good and the wheels and tyres sound. The black base is very clean apart from the usual wear on the 'differential' housing.
This is possibly one of the rarest models that you might have found in a box at your local toy shop.
You really will not see many of these around. Very rare and an excellent investment. I also have a similar model with an original box but that is a lot more expensive.
