LIONEL PREWAR SG 10E GREEN ELECTRIC ENGINE LOCOMOTIVE. This was part of my Dad's extensive collection, and was labeled as "Working" prior to him packing it away.I have no way to test it now, but have no reason to believe that it would not be running. Wheels all move freely with no cracks, and everything appears to be original. It could use a good cleaning and would be a great restore piece. 4300+ Feedbacks and 100% Positive.
