      Found this while I was cleaning the back of the A-45.

      Looks like LYNI.E Any ideas what this is?

      Thanks,

      Steve.

        I’ve wondered what that meant myself and what I found on it was; it was a trademark of the aluminum casting co. out of Cleveland from 1914-1986 and it is also a type of alum alloy.

            I believe Lynite (lie night) is a high strength aluminum alloy originally developed for pistons. The copper was theoretically better able to transfer heat from the dome of the piston. He added strength was a surprising bonus.
