Looks like your getting a shunt wound motor because of the field rating on
the motor. Not a minus, at all. Rust might not be a problem if the motor
is free and bearings feel smooth and tight. You might need a heat sink for
the controller (I'm not familiar with that one). IF the price is
right........ As long as there are no apparent "smoke holes" on the
controller, you really won't know until you hook it up and run it.
