Need help. Bought this lionel C&NW F-3 ABA at Wheaton Show. No box so am trying to find out its Lionel 6-xxxxx number and cataloge date so I can tell what features it has. Two motor power A unit is cab #4067A, dummy A unit is cab #4086C, and B unit is #305. All are used but in great shape with what looks like either factory yellow and green paint or a very professional repaint. Decals also appear factory. Rear of the A units and both ends of the B unit are black unpainted plastic. The lower areas(trucks/fuel tanks etc) of all units are black. No screen tops. B unit may have one electrocoupler. Units do not have cables between them. Power unit and B unit have small switches on the bottom. What are these for?
I can find what look like similar items in the 181xx and 36xxx (SF,WP,NYC etc) but no C&NW. Was this part of a set or maybe a special order by a Hobby Shop or RR model Club?? Has anyone seen another one?
Thanks, Bill Potterton
