Bentley Clutch: We send herewith a print of N.Sch. 4953 showing three large holes in the standard clutch casing for ventilation, on the lines of those provided on the Essex Terraplane. If these serve the purpose and do not cause whistling they will result in economy of cost and weight when compared with the Borg and Beck scheme. N.Sch. herewith.
