According to the circuit diagram there are certainly seperate RF stage trimmers for LW and MW on this set. It would be very unusual if there wasn't.

There are a bank of 4 trimmers under the chassis. TC3 (40pF) is nearest the tuning control spindle with TC4 (80pF) next to it. I'd guess from the greater value that TC4 is the one for LW but it won't hurt to try a small adjustment to peak both.
