Dinky Toys 284; Austin FX4 London Taxi
The Austin FX4 London Taxi was in production from 1972 to 1979 in 1:36 scale. It was usually black, sometimes very dark blue and in 1977 it was silver to celebrate the Queen's Silver Jubilee. Values are not great as there were very large numbers of them sold. I managed to get £5.50 for a nice boxed example in 2019.
