Very rare Lucas 584 day-night dipping interior mirror. This mirror was used on MG ZA and ZB Magnette, Sunbeam Talbot, and other high quality British cars of the 1950s. They were also sold as accessories and were popular on race and rally cars to prevent drivers from being dazzled by headlamps of following cars.
These mirrors are rare and highly sought-after. This one is new old stock, with a little patina, as the pictures show, but it is in beautiful condition. It comes in its original BMC envelope.
