To Hs.{Lord Ernest Hives - Chair} from R.{Sir Henry Royce}

Sunday the 9th. Dec. 1928.

Further to my letter of last night, DA.{Bernard Day - Chassis Design}
and I worked at the radiator support this morning, and came to the conclusion that for immediate application we could increase the stud to 5/16. Watch that the clearances are all right and use a rubber washer on the bottom instead of the steel spring.

[Drawing of a washer with dimensions <-- 1 1/2 -->, <-- 1/2 -->, A <-> 3/4 V]

This is the washer which will be the longest thing to get.

I think, if the distance piece did not allow the radiator to lift more than 1/16 the stud would not have broken.

The job is not coarse enough and we are altering it tomorrow to a bigger size.

There does not seem much the matter with the scheme.

R.{Sir Henry Royce}
