The link is wrong but the original article was published in Music Trades Jan.1, 1991. The title is 1890-1899: the American music industry comes of
age. If you Google the exact title of the article you'll come up with several links. The standard was decided upon by the Piano Manufacturers
Association. The whole article is a real interesting read. As far as the other reference, Google Bernard Pietsch. Paul Horn apparently contacted him
before recording in the pyramid and it was suggested that he resonate the Coffer and tune his flute to the note. He took a Korg tuner with him and
determined the frequency was A438. You can download a sound byte to hear it or you can buy the album if you can still find it. The album has some
really beautiful stuff on it and I am pretty sure after having met Paul Horn years ago that he has nothing to do with the NWO. Thanks. P.S. The
Bernard Pietsch articles are especially interesting and filled with equations, measurements and whatever you want. Just remember to honour the
copyrights of all previous mentioned people and organizations.
