Listing is for an MTH Premier Non-Powered  Santa Fe F-3 Diesel  "B"  Unit. This "B" Unit is from MTH Santa Fe F-3 A-B-A  Set 20-2219-1.  I had previously sold the (2) F-3 A Units and was going to use this B Unit with a different Set of Santa Fe F-7 Diesels, but no longer plan to use it that way so I'm selling it.  It is Open Box New having been removed from the Set Box when the A-A Units were sold. NOTE:  There Is No Box For this B Unit.  The "B" Unit has been attractively Detailed by having the Kick Plates; Steps; and Fuel Tank Fittings painted to match newer MTH and Lionel F Unit releases (see photos).  It was Never ran or used, so I'm listing it as Open Box New condition. Please Note:  I have moved the "Connecting Cable"  back to it's original factory position so you can see  that this "B" Unit can be used and connected in an A-B-A Set....Please see the last (2) photos I recently added to the Listing. 
I had originally relocated the Cable to inside the Shell because I "was going" to use this "B"  with a different Mfgr's.  A Unit - (I never used it as all), so I returned it to it's Factory configuration - Thanks for looking, please e-mail with any other questions and be sure to check my other Listings for more O Gauge Train Items.
