Multi-Speed Shutter Company
The Multi-Speed Shutter Company was a shutter maker based in New York. It also made the Simplex Multi-Exposure camera which made full-frame or half-frame exposures (800 on a spool) on 35mm film and used a fast Compound shutter (1/300 sec.). Multi-Speed's own Multi-Speed shutters were the fastest non-focal-plane shutters available in the early 20th century, with high speeds between 1/200 to 1/2000 sec. and low speeds between several seconds and 1/100 sec..
