Jesse,
      According to my tables SAE40 is Cu85 Pb5 Sn5 Zn5, or precisley what
Alan quoted for typical gunmetal.  So there you go.  To add anguish to
injury, as much as I dislike gunmetal, I have a full set of castings for a
fine large scale Corliss mill engine every man & boy of which is in red
brass.  :-(

Harry
