Awesome find!
As we all know, just about anything can be fully restored, if not, at least to some degree of originality.
Although not impossible but yes it may be difficult to have the radio and record player restored and totally functional.
The thing to consider is, are you willing to put in the amount of money $$ and or time to have this done?
That's the bigger question, that is if you want the original radio and record player to be fully functional.
If that task seems a bit much to tackle then maybe consider finding a good tech to accomplish this?
If not, then maybe remove the radio and install a nice stereo receiver, simular in size, as well as a turntable in place of the old one's?.
Also not mentioned are the console's speakers?......what condition are they in?.....you might also consider replacing those as well with new ones.
Whatever direction you decide to take, please keep us posted with updates, pictures, etc. on your progress.
I know for a fact that "I" would like to see the progress and finalization of the restoration.
Just my $0.02
Good Luck!
