Korona Cameras, Lenses, Photographic Goods, Gundlach Optical Co., (Rochester, NY), dated 1899, ~5 ½"x7 ½", 36pp
This catalog, unlike the 1901 Gundlach Catalog, was made well after the acquisition of the Milburn-Korona Co., and so contains that company's extensive line of leather-covered Koronas, but no wooden field view cameras as yet. Those would come in the 1900 Gundlach Catalog.
There are two catalogs of Korona Cameras for 1899 in this collection: Korona Cameras 1899 LP1193 (blue cover) and Korona Cameras 1899 LP484 (tan cover). Even though the both have almost the same dimensions, and have the same number of pages (36), they are not identical. The prices, usually the most urgent reasons to produce a new catalog before the year is out, appear to be unchanged. Small differences and sometimes new items can be found throughout the camera and lenses sections.
It is interesting that they produced two printings for what appear to be very minor changes.
