With reference to Mr. Royce's telegram (copy of which I gave you last night), asking for a test with 6 : 1 compression pistons, we require 1/4" on the top of the piston, Part No.E.13289.

Please have a set of pistons made without altering the cores for the first test. We will give you the position of the rings when we have made sure that they are not running into the counter bore.
