Dave, you said:

Hmmm.  I have seen dozens of references which show 63.0%/37.0% to be the
eutectic composition for tin-lead binary alloys, and this is the first time
I've seen otherwise.

Anybode got a new edition of Hansen? I'd like to see confirmation,
otherwise I'll keep my solder post as close as possible to 63% tin. We'd
all be able to save some money if you are!
