 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.  :-( Regards,
Harry

Sure and you will paint the engine anyway Harry, so the colour makes little 
difference.  One of the reasons I wanted to paint the model Bernays engine I 
just finished was because of the several shades of brass/bronze I used in 
its construction.  As it happened, the most obnoxiously red piece was a 
handwheel for reversing and a tall column for the crosshead guide.  As it 
turned out, I discarded the handwheel because I realized the engine would 
probably not run in reverse and I used "gold" paint to cover the colour of 
the crosshead guide.
