Thanks for looking Terry. Mine is a 1120 series 10. A fellow gave me the chassis and speaker keeping the cabinet. I did get four knobs with it, two of each shown in picture. But I don't know about them because all four are D shaft. They don't fit right, seems to cock and for sure one doesn't seat right on the round tuning shaft. That big white knob is for bench use. This set really sounds good.

You might want to try David Frush for knobs. He knows his stuff.
