1) T4 and LW secondary LO coil in series with T6 is shorted on MW. Solder a jumper across switch.
2) R4 and LW primary LO coil is shorted on MW. Switch resistance here will not so much detune. Only short switch here if step in one isn't enough
Actually, I tried your suggested process, and the LO HF end shifted up fifty KHz or so, the switch contacts looked quite black and dry so I gave them a clean with CTC and some vas to stop them oxidising again

Bingo! I snipped one lead and measured C it was showing high. I set the oscillator trimmer to mid value, (about 30pf) then replaced the capacitor with a black cap ceramic the correct value. The Local oscillator can tune so I'm now able to line it up with the dial. Next is full alignment, Job for another day!
Top advice Mike.
Thanks,
Amie.
