I have two MTH Proto 3 F3's available:
MTH 30-20667-1 Railking scale Union Pacific AA. The set came with ABA but I am selling for a friend who just needed an extra B unit. This is a Proto 3 set that was shipped in December 2019. Powered A has been test run but unpowered A has not been unwrapped.
I am asking $375 plus shipping.
MTH 20-20764-1Premier Santa Fe F3 powered A. This is a single A Proro 3 engine with very little run time and is in like new condition with original box, inserts and shipper.
I am asking $275 plus shipping.
