Rectus
Rectus was the name of a shutter found on some Japanese cameras from the 1950s. It existed at least in two variants, with B-1-200 and B-1-300 speeds. According to a post in the Classic Camera Repair Forum it was a copy of the Prontor II. According to this page at Japan Family Camera, it was made by a company called Fuji Seimitsu (富士精密), together with a shutter called Ceres. (Today there is a company called Fuji Seimitsu, but its website says that it was founded in 1962.)
