With reference to the modified servo gears in which we have larger diameter pinion, we understand that these were fitted on chassis 14-EX some time ago, therefore should be glad if you would look into the matter with a view to issuing a Standardisation Sheet so that we can introduce the new gears on production as the larger pinion will help considerably in obtaining silent gears.
