Will you please instruct for 25/30 production con. rods exactly the same as on the large bore Bentley. We had previously asked that these rods should differ from the Bentley in not having the oil hole drilled for lubricating the cylinder walls. We now wish to have this oil feed which can be drilled in any rods already finished. Hs{Lord Ernest Hives - Chair}/Gry.{Shadwell Grylls} | ||
