Need a selectone 610 (oscillator) coil

[Robert Meader]

I recently got a shield grid 9.  I have been looking for years only to find this has two selectone  620 coils and no 610 coil.  Anyone have a spare Selectone 610 coil ?  Another possibility  is if  someone has an inductance meter and could measure the inductance of the three windings I could make one.
