   Jim - thanks for the "911metallurgist" link about tin assaying.   
   I knew of "911metallurgist" and for sure the index page of the website -   
   but had not a thousandth part of any idea how much stuff there is there   
   and how high quality it is.   
   I'm finding loads and loads of very relevant interest, now I know to   
   look.
