Original manual overdrive 3-synchro gearbox from Mark 2 or Mark I. No history is known about this gearbox, but it's a tough old Moss-type box, so it is probably usable as-is, and certainly a good candidate for refurbishing. It has been stored indoors.
We have an extensive stock of Jaguar saloon parts from Mark I, Mark 2, S-type, 420, Mark VII, Mark VIII, Mark IX, Mark X and some Series I XJ6 parts, pretty much anything a Jaguar restorer could want!
