1939 Zenith "hook" Push Buttons - Radio Knobs
The long hook pushbuttons go on the left of the dial. If your radio has 8 pushbuttons on the left, then two more are needed for the right side of the dial.
The short hook pushbuttons are located on the right side of the dial. They push onto a thin switch slider. Look for them below listed in the "Related Products" section.
If these are missing on your radio, then probaby the part of the switch that they push onto is broken also.
These slides have a little brass eyelet in them. Four of the slides have the eyelet closer to the short end, and two have the eyelet closer to the long end.
If your radio has 6 of the short pushbuttons on the right of the dial, it also has 6 of the switch slides. If your radio has 8 pushbuttons on the right of the dial, it still only uses 6 switch slides. The 2 buttons to the left of the 6 short buttons are long buttons for the On/Off switch.
See the switch slide description for instructions on replacing them.
