Topic: 1892 book on the history of piano construction
Ran across this while researching my new old Chickering, and thought it might be of general interest: "A Noble Art: Three Lectures on the Evolution and Construction of the Piano," published in 1892 and now available as a free download. Discusses the various contributions of Broadwood, Erard, Chickering, Steinway et al to what was then the modern piano. Not, in terms of technical depth, the equivalant of Five Lectures on Acoustics of the Piano, since it has a broader subject, but still, it's about 160 brief pages on the history of the piano written not long after cross-stringing and a cast iron plate were fairly recent innovations:

Includes some illustrations of interest, such as a plate of Cristofori's original action and an early Broadwood action.
