Our records on this one are thin since it hasn't come through our own counter yet, but the part number and description are clear enough: it's a reproduction of the original Lucas adaptor, built to work with the older BPF-base bulbs. If you're restoring a period headlamp assembly on one of these older singles, this is the small but necessary bit that often gets overlooked until the old one crumbles in your hand.
Give us a call before ordering if you want to confirm it matches your specific light unit - these older Lucas fittings can vary more than folks expect, and we'd rather get you the right one the first time.
