USED Reverse E-Unit XA10587E:  This postwar E-unit is a 4-position, or 4-step type with 2 front tabs as well as 1 rear screw mount for attachment in diesels as well as many tenders.  It has been deep cleaned (not sprayed) with a black patina steel frame, working coil, and excellent condition drum.  Scant wear; no wiring. Unused New reproduction upper/lower contact fingers with tension close to the originals. The coil works and tests to spec.  The unit, with drum and fingers, cycles nicely and consistently without hang up. The 4 steel tabs for the finger contact boards have been left straight for ease of assembly and will need to be carefully twisted once wiring/soldering is complete.  The unit comes with a mounting screw S230-B.  So, please review the photos carefully as they clearly show the stated condition in detail.  I will be happy to answer questions, I just kindly ask that you inquire prior to your bid.  I do combine shipping.  Thank you!
