American Antiquarian Society (early machine tools ads and broadsides)
Back in 2012 I found, on the internet, the American Antiquarian Society
It had some early Bement & Dougherty illustrations from 1866.
Also a Phoenix Iron Works gear cutter (1860-1865) and Trumbull Iron Works illustrations from the mid 1850's.
I had posted this on the PM. I never really explored the American Antiquarian Society site.
It was not an easy site to explore (for machine tools) as it is mainly organized by the lithographers.
I found this on the site. Old ads and broadsides that had been collected by William Allen.

Most of these makers I have known about, but I had not found illustrations of some of their machines until now.
