I have a brand new never run F3A and F3B Proto C&NW set of engines. A and B are powered.
They are not F7s but F3s. Beautiful engines. A has road number 4064 and B is 4065B.
If interested let me know.
The engines are DC only and would have to be converted if you want DCC. Proto 1000 engines
are great runners with can motors and flywheels but original gears were prone to cracking. These gears have not been changed and are still in factory shrink wrapped boxes. These gears may not be cracked but many have.
Not a hard repair.
