General electric Tv from early 1950's

[enrico6v6]

Hello! Cleaning a basement I found this old General Electric Tv, I want to restore it but ther is no model number on it, unfortunately tags and back cover are missing, like some of the tubes. Out of this it looks to be in decent shape. It shows an uncommon EHV stage, with three rectifier tubes. Main rectifier is selenium type. If anyone have an idea about its name, and/or have the schematic or the tube list, please let me know! Thanks! Enrico.
