19th century piano history

[Scott Jackson]

Pianotechies,
I just stumbled across some re-prints of articles about piano construction
and tuning in the 19th century. Most articles are in English, but some are
in French and a couple in German.

Does anyone know the owner of this site, or the significance of "three sixes
in a row"? It is identified only as "Oldies".
