Romain Talbot was a wholesale dealer in photographic goods in Berlin, from 1855.At least for some of the period the firm was active, Talbot did not make cameras, but sold them under his own Errtee ('RT' for Romain Talbot) brand. McKeown lists a few folding cameras for plates and roll film, including rebranded Balda and Foth cameras. There is also the Errtee ferrotype button camera of about 1910, for one-inch ferrotype buttons, incorporating a developing tank. This has a 60 mm f/3.5 or f/4.5 Laack Schnellarbeiter lens.[1] The base of the camera has three processing tanks, the exposed plate drops down the chute. George Eastman House has a wooden (or wood-covered) version, decorated to look like a miniature cannon, complete with wheels.Another street or fairground camera with a Talbot-branded lens, this one for postcard format pictures, also developed in the camera, was sold at auction by Rahn. Talbot himself died in 1909. Talbot dealt in other goods besides cameras, including motor accessories and bicycles, and the company had an outlet in London.[8] [9] Talbot (in person and the company after his death) held patents relating to bicycle equipment and other inventions.
