Abstract
Abstract An adaptable mounting for alternative forms of telephone dials comprises a mounting bracket which can be attached to a telephone housing base in either of two alternative positions. In one position a spacer is positioned between the bracket and housing base to raise the bracket. Adaptors are provided for attaching to the top ends of the bracket cover to accept one form of dial, an alternative form of dial being mounted directly on the bracket cover.
