USED Prewar O Gauge E-Unit - 2 Screw Mount:  This prewar E-unit is a 4-position, or 4-step type with front 2-screw platform, and upright lever.  It is used on steam engines in the few years prior to WW2. Note: This product is not intended for use in diesel engines or tenders. It has a clean, steel frame with a few blemishes in the patina, stable platform, working coil, excellent condition drum, New upper and lower reproduction contact fingers; the fingers have tension close to the originals and are not the rigid type. The coil tests to spec and the unit cycles consistently without hang-up.  Does not include the 2 mounting screws.  The coil post has some loss of patina due to removal of rust associated with the past solder joint. The 4 steel tabs for the fiber contact boards have been left straight for ease of assembly/adjustment and will need to be carefully twisted/bent once wiring/soldering is complete. Please review the photos carefully.  I will be happy to answer questions, I just kindly ask that you do so prior to your bid.  I do combine shipping.  Thank you!
