- The horn horn appears to my eyes as a RCA multicell / the horn-drivers in the background are RCA ( field-coil types ) from the 1930s. They'll either be MI-1425(s) or MI-1428(s).
- The model difference ( I believe ) is mostly in the voltage necessary to energize the field-coils . In case you don't understand, the drivers have no permanent magnets / so without a charging voltage they won't work .
- The bass bin appears to be a Shearer horn from the same era . The woofers ( therefore ) are also likely to be RCA .
