I have my father's binder. I believe it to be a 1920's McCormick-Deering.
The tongue has been cut off to allow it to be pulled by a 9N. Otherwise I think it is complete except for the canvas and the wooden parts of the reel, however it has been setting outside for many years. I did see one panel rusted through. There may be other wooden parts which I'm not aware of.
Is there a restorer somewhere who would be interested in it? My email is open.
