ENGINE RUBBER MOUNTING RUBBERS. xS005 (handwritten and crossed out) XS005 (handwritten) We understand that there is no limit on the diabolo rubbers for the engine mounting as regards length. The limit should be ± .002". We suggest that they are accepted from the makers with a limit of ± .005" if they will not undertake to supply them at ± .002", and that the final length should be produced in the Works.
