This finger wheel was fitted to GPO telephone dials from 1967 onwards. Introduced with the telephone 746 & 741, it was also uses on refurbished 706 and 711 instruments. The wheel fits a standard GPO dial 21 and may fit other GPO style dials. It is constructed from clear plastic.
Please note: This finger wheel should only be fitted to dials using a countersunk screw. If your dial uses a screw with a flat back to the head, then please see our other listings for a variation to accomodate flat backed screws.
