I see from some of the schematics you have referenced that it may have a double primary winding or a single primary winding…I had the same issue with a Rogers chassis last year which had the single winding primary on a similar coil form.
The primary winding was chewed on by a mouse…so I simply removed the bad winding and placed some tape on the coil form and added about 80 to 100 turns of 40awg wire to form a new primary loop. The wire loop width was about 1/2 of an inch and close to the secondary winding…not the prettiest job but it worked well. The DC resistance I think ended up being around 30 ohms?…I will try to dig up a photo of it but in this situation this type of broadcast coil is not that critical for the BC band.
