MRC PEDAL GAP PLATES The pedal gap plates of all models are at present produced as aluminium castings machined where necessary, those on Wraith and Phantom III. being of two piece construction, whilst a single unit is used on Bentley. The manufacturing time allowances and factory costs of these parts are given in the attached sheets, and it will be appreciated that the parts are extremely expensive having regard to the light duty which they perform. The single piece construction used on Bentley is the cheapest design of the three, and would provide an appreciable saving if it could be applied to the other chassis, particularly if the one piece were made common to all models. It is proposed however, that design should be investigated with the object of providing a pressed sheet metal pedal gap plate, which would require no machining apart from possibly drilling or tapping, and which would offer the maximum economy. It is, of course, not possible to arrive at definite tool and factory costs for sheet metal pressings until a scheme is available, but it would appear that the saving may approach 10/- per chassis.
