Stromberg-Carlson FR-503

Hello. I am not looking to sell this, but I am looking to find out some information about a radio console that my grandmother gave me when she moved. What I know is that it was custom built for a doctor that owned her house previous to her and he included it in the sale of the house. There are matching dining pieces that other family members have. I don't know what year it is. I'm pretty sure the speakers were replaced many years ago. The radio works great! I'm not sure if the record player works, but I'm pretty sure that it does not. Other than a missing knob on the front and some water spots on the top, it is in great condition. Just wondering if anyone could tell me anything about it (i.e. year, value, a common item?, etc.). I found this board when looking up the model# and someone discussed the model before. Here are some pictures (they are clickable):
