| V4432 To BJ. from Hs{Lord Ernest Hives - Chair}, Hs{Lord Ernest Hives - Chair}3/LG1.11.22. VALVES. Referring to your BJ11/H27.10.22 attached. We have recently standardised replaceable valve guides. This will not prevent wear but it will make it easier and cheaper for the parts to be replaced. We are also experimenting with various materials and dies in order to try and find a more satisfactory material. Hs.{Lord Ernest Hives - Chair} | ||
