This is a very rare NOS original 2-adjuster headlamp bowl assembly, complete with bulbholder, inner chrome retaining rim and adjusters and a NOS wiring pigtail. It's a Lucas F700 MK X for 7-inch headlamps.
It is correct for just about every British car made with twin headlamps from about 1959 until 1985 or so, including Sprite, Midget, MGA, MGB, Austin-Healey, Jaguar, Land Rover, Daimler, Triumph TR and Spitfire, Rover, Hillman, Sunbeam, Mini, Austin, Morris, Morgan, and everything else you might think of. It will fit and work perfectly with earlier British cars, but technically they should have the earlier, three-adjuster style. This one has two. It is in perfect, brand new condition. We a very limited supply in this condition, but do have a number of good used units to match, as well as brand new Lucas items in the box (although these are not as nicely made as this NOS one!). The new ones are sold as a pair for $65. This original one is correct in every detail, as the pictures show. Email us if you are interested in one of the other options listed above.
