Looking for vintage radio schematics (AGS-LOWBOY; Music Craft RG-100)

I tried Google, I tried Sams Photofact, but found nothing. :-(

I have two table-top vintage radios:

American General Trading (AGS-LOWBOY) (6-tubes)
Music Craft (Rosgol Industries) RG-100 (7-tubes)

Both look like they may be from the mid 1960's.

It's a long shot, but if anyone can help I'd be very happy!
