I posted several days ago on the WANTED forum looking for a replacement coil.  See https://philcoradio.com/phorum/showthread.php?tid=20069.  After reading the posts there and discussing with Terry via PM I may consider trying to rewind the open coil.

The open coil is the small primary winding.  I have posted several pictures of the coils condition.  In PM discussions with Terry it looks like I could rewind with 25 turns of 34 gauge wire and the direction of the winding is not of concern.

My problem is the removal of the old winding and what looks like the melted remnants of the nitrocellulose material separating the two coils.  Also wondering if the secondary coil may be damaged by the melted remnants although it does show continuity.

An comments or quidance is appreciated.

Thanks, Bob
