If you need to have the armature or field rewound I believe Jim Diehl in Cadillic, Michigan is good and reliable. Last year I had him rewind the fields and armature on a Sparton; he did an excellent job. He also installs a small bearing in the mounting base for the lower shaft of the armature to run on instead of relying on oil on the felt.
