After Desert Storm Gulf War, a Marine who fought in the war spotted a
bottle of Protek CPL on my desk.  He said that's what he and some other
Marines used to keep their handguns and rifles firing, because the
standard lubricants all attracted dust, sand, and eventually locked or
siezed the firing mechanisms.  He didn't remember how they got the CPL
over there; but it worked.

As for MSDS's, since they are designed to fulfill Right-To-Know
legislation and public safety information, it might not be necessary for
the maker to list the contents unless it contains toxic compounds or an
actual accident has occurred with its use.  Sometimes they are allowed to
list contents as "Trade Secret".  One of the web MSDS sites might list an
MSDS for it, or the manufacturer might provide an MSDS; I don't know. If
anyone wants a list of MSDS web sites, ask; or contact an industrial or
college environmental safety office.

Dean,

Our modern idea of a "standard temperament" did not really exist from the
early 18th century to the early 20th century. During the 16th and 17th
centruies the standard temperament on keyboards was 1/4 comma meantone,
before that on organs it was Pythagorean, either straight up or modified.
Between the early 18th and late 19th centuries the question becomes a
little more difficult - and interesting.  Use you judgement and don't be
shy.
