Grimer,
Just wanted to mention, I looked up Lang Radio in the Riders Index. There are Lang Radio schematics in volumes 1,2,3,5 and 6. None of the schematics matched your chassis layout. It seems your radio has an early circuit. I did notice that many of the Lang radios were designed to work off the old 110 volt DC power grid. Maybe someone at ARF has seen your Lang Radio.
