Field coil Interesting find

Any information on this?

Must be an old loudspeaker with no permanent magnet but a magnétising coil, as far as I remind the magnetisation coil was used as an inductive filter in the power supply of the radio set, but yours have an AC plug similar to mains ? Of course magnetic field mus be constant not alternating I think you should look into the base to see what is inside that box.

Frank Reichmann​

Oxford Radio Company of Chicago came into existance sometime in the 1920's, but I haven't been able to locate its exact origins, so I won't rule out an eariler nascence. The earliest officer I can find a record of is Frank Reichmann. Reichmann was an radio engineer and was quite active in what was then, a new community: radio. Besides patents and radio designs, Reichmann wrote articles that educated the public on how radios and loud speakers worked. These articles were distributed and printed by many newspapers across the country. Some of these newspapers have a special "Radio Section", much like a "Sports Section". Reichmann was an engineer and inventor. I found references to him being the chief engineer and general sales manager, but I found nothing to indicate who ran Oxford Radio, or who owned it.
