TSK is a name on some Japanese leaf shutters of the 1950s. All the examples observed have B, 1–200 speeds.
As the Elbowflex and the Princeflex were sometimes fitted with a TSK shutter and were made by Tōyō Seiki Kōgaku, it seems likely that TSK stands for Tōyō Seiki Kōgaku and that the shutters were made by that company. Further, the TSK shutter on the Alfaflex and Cosmoflex is marked not only TSK but also TOYO S.K.CO.; however, nothing is yet clearly known.
An unrelated TSK shutter, giving 5–250, B, T speeds, has been observed on a Baby Germa pictured in Sugiyama.[1] In this case, TSK certainly stands for Tōkyō Shashin Kōgaku.
