This finger wheel will fit all GPO dials number 21, plus some other GPO type dials. It was introduced with the telephone 746 in 1967, but is also used on tele 741, refurbished tele 706 & 711 and others.
Please note: There are two variations of this finger plate which depend on the type if screw used to fit them to your dial. This item should only be fitted using a screw with a flat back. Please see our other items for a similar finger wheel that can be fitted using a countersunk screw.
