1953 Motorola

[fishmanejr]

Hi all,

I'm new here and am posting to help my parents. They're cleaning out their house and have what I believe is a 1953 Motorola 21K4, serial number A 249720. I know nothing about old televisions. My parents would like to confirm this set's identity and potentially sell it. Any information on proper ID and value would be appreciated! Here are some pictures. The set looks to be in decent shape from the outside with the exception of the finish wearing off on the top and sides of the wooden case.
