Ansco Speedex
Speedex was the name used by Ansco in Binghamton, NY, for a series of 6x6 format folding cameras. The first Speedex models appeared in 1940, under the name Agfa Ansco, the brand in use in that period. The original models were produced in the US, however. As with other Agfa Ansco products, the film size may be designated B2 (the Agfa designation); but this is equivalent to 120 film. The Speedex B2 has 85mm f/4.5 Agfa Anastigmat lens. The shutter has speeds from 1/2 to 1/250 shutter speeds plus B and T settings. There is no interlock which prevents double exposures. (Camera-Wiki)
