This car was released by Dinky in 1953 and
remained in production until 1964.
It was sold under three model numbers. Up to 1954 it was 23h when it switched to 234, in 1962 it was changed to 209. For most of the production run the wheels were painted, with spun hubs coming in 1962 being replaced with plastic hubs in the same year, consequently spun hubs are very scarce.
Most cars are blue with a yellow nose cone, you will see some with a yellow triangle on the nose and these too are scarce and valuable.
