This is a new Lucas SF4 Fusebox, correct for Jaguar XK120 and many other cars of the 1950s. This fusebox will also fit XK140, XK150, Mark VII, Mark VIII and Mark IX but these models do not need the top cover. We sell the fusebox without the cover for $80, and covers alone for $65.
This is a correct, perfectly made part, made in England on the original Lucas tooling. Some say Lucas, others have a Lucas lion.
We also have NOS and unmarked new SF4 fuseboxes; see Related Products below or contact us.
