| COPY N/W - Hd.{Mr Hayward/Mr Huddy} Br1/W21.8.33. Re: Technical - 20/25 HP. Clutch slip. -------------------------------------- We have received a memo from Hs{Lord Ernest Hives - Chair}/Gry{Shadwell Grylls} informing us that a complete circular gauge should be used for testing the slackness of the serrations of the clutch. Will you please let us know if you can supply a circular gauge for this job. If such a gauge is available perhaps you will be good enough to send it forthwith and we will let you have an order.
