This is a perfect, new production Lucas starter solenoid SRB341 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 picture. It is the correct starter solenoid for later Mini, Midget (1500 cc), Land Rover, Triumph Spitfire, Morris, Austin, and many others.
This part is very similar to the SRB 325 solenoid, which we also sell, except that it has an extra terminal (we believe for use in cars with an external-ballast coil).
