An RCA find, some info needed

[coffee123]

So dad frequents the rose bowl swapmeet among other things, and he has picked up a few radios for me, some of which i have yet to unbox and go through....but he saw this and coudnt pass it up as he wants to teach me some of the woodworking/resto skills he has which im pretty stoked about. But i wanted to get some info for this bad boy, see if anyone had a schematic

Its a RCA 16T3. The cabinet is absolutely gorgeous, and needs very very little work...only 2 or 3 nicks, and the obvious on/off swith someone added in the upper left corner, prolly cause of the original switch failing. It too has ben replaced with a regular pot, and the knob is MIA. So i need to find a knob, and figure out if the original style switch is available, or if i can just use a nothing special on/off/volume control....problem is finding the proper knob and shaft size...Also has a TV input, so im guessing early maybe mid 50's?

So ya, thoughts, comments? im have this posted in tube stuffs at audiokarma too :p
