Hand-held stereoscopic camera patented (1891) and manufactured by Jules Richard (1848-1930), Paris. The first model, launched in 1893, had twin f/8/55 mm lenses and used 45 × 105 mm (1 3/4 × 4 1/10 in) glass plates in a twelve-plate cassette. The design was so successful that 78 regular models, plus seven larger-format (60 × 130 mm (2 1/4 × 5 in), 70 × 130 mm (2 3/4 × 5 in) ) ones, were issued over 60 years. In all, 52, 000 were made. The last, top-of-the-range F40 rangefinder (1939, introd. c.1946), of which 5, 000 were manufactured, took 21 image pairs on a standard cassette of 35 mm film, with f/3.5/40 mm lenses and a shutter speed of 1/250 s. It had a matching stereoscopic viewer, and sold in the USA as the Busch Verascope F40.
