Dated - April 1900
This catalog is interesting if only that it contains the gaudiest paper of any in this website, as well as the useful "Camera Shutters that Shut". The cameras are Gundlach-Manhattan leather-covered Koronas and Kodak cameras only, so no wooden view cameras (sniff). It does, however, have a very useful translation of older Korona series designations from the 1890's to the newer series designations (pages 17-20), to wit:
Korona Old/New Series Designations
| Series I-B | Series 1000 |
| Series I-A | Series 2000 |
| Series I | Series 3000 |
| Series II-B | Series 4000 |
| Series II-A | Series 5000 |
| Series II | Series 6000 |
| Series VI | Series 7000 Korona Long Focus |
| Combinations of plates size and
lens are numbers in the new series e.g., Old: 4x5 Korona Long Focus with rectigraphic lens = New: 7615 |
