Here is a RCA Radiola Special from 1923 made by Wireless Specialty Apparatus Co. The radio is in a fitted case, I think this must be custom made for it a long time ago for portability. It has a built in antenna in the lid and storage compartments for batteries and headphones. The external battery posts are wired up and I powered her up that way, the wires can easily be routed to the battery compartment. We have another at 1420 but I could not get that one, the radio may not tune that high? The variometer turns freely and a new grid leak resister is installed. The only thing I have done to this radio is wire up the battery posts. Please check the pictures they will show it off well. The case measures 16″ x 10 1/2″ x 7 1/2.
