And, to add to the muddle, A-440 is a relatively recent standard.
According to the always-reliable Wikipedia:

"Prior to the standardization on 440 Hz, many countries and
organizations followed the Austrian government's 1885 recommendation of
435 Hz. The American music industry reached an informal standard of 440
Hz in 1926, and some began using it in instrument manufacturing. In 1936
the American Standards Association recommended that the A above middle C
be tuned to 440 Hz."

It's worth noting that Edison got out of the record business in 1929 --
only three years after the American music industry's "informal standard"
was adopted.

Peace,
Paul
