I've a choice of two medium wave local oscillator coils. The one close to the metal can is a genuine Denco Maxi-Q component. Range 2 is the MW band and the oscillator coil is coded red. Blue is the aerial coil and yellow is the RF interstage coil.
The coil on the right is I think not a genuine Denco part, however, it is red and has the number 2 on it so it might be OK.
For the long waveband I'll try that cheapo trick of switching in a 300 to 390pf capacitor across the oscillator tuning winding. Check out the circuit of the Pam TR26 to see how it's done.
