• Farm Radio. The popular set from the TV series "The Waltons".
  
  The cabinet is similar for the following "Walton" models:
  12-S-232
    9-S-232
    9-S-232AT
    8-A-232
    7-S-232
    7-S-232T
    7-J-232
    7-J-232T
  They are looking all the same. That's why all of them are called "Waltons" although only one thereof was in the play.
