Everything you need is still available. A large majority of the old coils were wrapped with a cloth wrapping and then dipped into a varnish, however, this wasnt a long term fix and the wrapping material can still deteriorate and eventually the windings could short to the case. Same on the armatures, there are "insulating stacks" inside of the armature and they are made of a paper like material that eventually will get old and can cause shorts.
I can help you out with any component part you need or a complete restoration If you will private message me.
Thanks,
Ken
