This might be of interest from 2012

The link that Gerald published at that time (at box) is no longer 
active, but here is a text version of the letter:

> In the early days of Steinway, only God knows what pitch was used as a design parameter—probably either “Stuttgart” or “French” pitch.  During the 1870s it seems to have been rather high, varying from 454 to 458.  In 1891, however, Steinways must have agreed to and used 435 until 1926 when the International Standard Pitch of a-440 was adopted world-wide.
