My first thought was the "25" indicated the 25 meter band from 11.5-12Mhz. But then I re-read and saw you wrote 25 cycles, so I don't know what that's all about. AC power is generally 50 or 60 cycles. As for identification, Airline was the label used for Montgomery Ward radios. They bought OEM chassis from RCA and others so it is generally hard to find schematics and info with the Montgomery Ward model number. You usually have to identify the original manufacturer's chassis by visual inspection, comparing the layout and tube complement.
