This is a perfect new Lucas 5SJ windscreen washer bottle and bracket. It is a nicely made part, nicer than most of the reproduction British parts made today.
It is the correct part for Jaguar XKE or E-type 4.2, later Mark 2, MK II, Mark X, Daimler 2 1/2 and 250, S-type, 3.4S, 3.8S, Morgan, Alvis, Triumph TR250, Pantera, Humber, and a host of other quality British cars made during the mid to late sixties and early seventies. It will also work in any car that has 12 volt electrics, and would be a good retrofit for earlier cars with glass washer bottles.
They now come in a new production red and black Lucas box, slightly different from the one pictured.
