Ron: Found these in that trailer and thought of you. Looks like they may need rewrapping? Dan
I have several milk cases full, look just like that

They are NOS Ford replacement starting motor field windings. You sometimes see these at swap meets. Obviously, they came from an original stock of Model T parts from a Ford dealer.
The Model T starter was very robust, would tolerate much abuse, these were commonly never used and survived.
Today these starters are 90+ years old and badly in need of proper rebuilding.
I have several in my shop, but would never use them "as is" because the cotton "narrow fabric" wrapping is rotten. BUT, they are a great place to start if you have the patience and perseverance to rebuild a field winding to use in a rebuilt starter. Rebuilding used field windings is a very dirty nasty job. From a cleanliness point of view these are very easy to disassemble, re-wrap with new cotton tape, and seal so they can be reused.
Here is a photo of a rebuilt field winding.
If these field windings are for sale, as a starter rebuilder, I would certainly buy them.
Please let me know if they are available?

Would only the outer wrapping have to be replaced, or would the coils have to be unwound and rewound with some type of insulation between windings, like a magneto field coil?
When using a NOS field like the ones above you only have redo the narrow fabric wrapping. The internal paper insulators will be good. In my experience when doing a used field sometimes rework is required on the paper insulators, but you do not have to fully uncoil them.
