McKeown's Cameras says Folmer & Schwing Co., Rochester, was Kodak's label from 1905 to 1907. Then it became Folmer & Schwing Division ot of Eastman Kodak until 1917 and then Folmer & Schwing Department of Eastman Kodak Co. until becoming Folmer-Graflex corporation in 1926. Thus, Dagors, Tessars, and their contemporaries would be authentic.
