This is a perfect, new production Lucas SRB316 starter solenoid in its original box. These solenoids are once again being produced in the UK under Lucas license and supplied in genuine Lucas boxes, as shown in the pictures. It is the correct starter solenoid for most six-cylinder Jaguars, including XK120, XK140, XK150, E-type, Mark I, Mark 2, Mark VII, Mark VIII, Mark IX, Mark IX, S-type, 420, 240, 340, Daimler 2 1/2, 250, SP250, as well as early MGB, Triumph TR2, TR3, TR4, big Healey, Land Rover, and many others.
It is a beautifully made part, genuine Lucas, and far nicer than most of the reproduction British parts made today. I guarantee you will be pleased with it, or send it back for a full refund.
