[Signature] R H GRY{Shadwell Grylls} P 2 BM 2nd. Gearbox. With regard to the bolts which hold the selector rod plunger housing to the diaphragm of the box we believe that we have seen lock nuts used on these. Our drawings do not appear to show the depth of the nut intended but in any case if they are found to be lock nuts would you kindly instruct full depth nuts unless there is any reason why this cannot be done, in which case we should like to be informed.
