The dial on that is the same as the dial on my RA-108 Mansfield. The colors on yours are still OUTSTANDING. My colors have faded. My RA-108 is from 1949. Original ad for the Club 20 located at below link if you scroll down. Hard to tell exactly what dial is on it, but sure looks "busy" like the RA-108 dial and the one you have pictured above:
