Photomicrographic Equipment and Micro Projectors, Bausch & Lomb Optical Co. (Rochester, NY), undated c. 1920, ~6½"x9¾", 56pp
This catalog is undated, although coded: "C-2, VIII-22, 20m. The equipment could be from a rather wide range of date. It is later than the 1907, 1910 and 1912 Bausch & Lomb catalogs, since those years indicate the presence of a branch in Frankfurt, Germany, whereas this catalog does not. It is identified as generally c.1920, but it could be that the VIII-22 in the code refers to August 1922.
