VALVE SPRINGS - P.II.

We wish to have all our cars, except 22-EX, fitted with tappet springs to Hs.{Lord Ernest Hives - Chair}502, and single valve springs to E.81550. 19-EX and 25-EX are at present correct.

To 22-EX we should like fitted the stronger tappet springs Hs.{Lord Ernest Hives - Chair}502, and double taper valve springs to Lec.3136 (Hs.{Lord Ernest Hives - Chair}688 and Hs.{Lord Ernest Hives - Chair}665), as fitted to 58-GN.

When cars come into the shop, will you please see that this is done.
