Those 1951 models are listed in the index on PhilcoRadio.com. Most of the sister radios are listed there as plastic. From your photo I am guessing that someone may have painted that and it was originally a brown one. They are a sharp set, there were some cool sets in 51 from a style point of view. If you pull everything out and off that cabinet maybe that paint could come of with a soft brush and soapy warm water, maybe soak it. I am not sure if you want and paper labeling on it to stick around though. How does the chassis look?
