Very rare mid 1920′s national airphone radiotrola ‘braby grand’ radio. Has a gt-1 monodyne single control tube set enclosed in a cabinet, cabinet has additional compartment for headphones, tubes, etc. It appears that this radio was only advertised by national airphone for a limited time in the late months of 1924. I could only find one other example on the internet which was described as the only known example to exist. 11″ wide x 7 1/4″ deep x 7 tall. Radio is in excellent condition overall. Exterior of case has some scuffs, rubs, and fading. There is a long split and lifting to covering on backside (see photo). Interior cabinet has some fading and lifting to covering. Tube set has some scratches and wear, the front has some separation/lifting but may reset when retaining screws are tightened (screws are missing). Tube included is for display only, interior rattles. Radio has not been tested, unsure if operating properly.
