The middle dial above the model number is loose and does not work, the inside doesnt move when you move the knob. Some other knobs are loose, the top door to get into the unit pops up, I believe this may be fixed once all the screws are added to the back to secure it to the back panel. It has scrapes and scuffs for its age, plugged it in and nothing seemed to happen. Once again this doesnt work, it would be a nice project for someone to fix. The knob on the right appears to move with the dial on the inside when I tried it. Vintage HTF National NC-57M Radio Reciever For Parts Or Repair.
