Swindell}2/AP.27.11.36. Will you please order for use on the Ph.III. test bed engines which have obsolete type of Fabroil idler gears and to which the present standard idlers cannot be adapted; 4 idler gears E.84853 complete with sleeves E.84851. Several of the existing idlers for the above engines have cracks which start from the lightening holes, will you therefore instruct that the idlers you order be left solid.
