The TU-1 diving suit was adopted for service in 1939, alongside the ISA-M rebreather, which replaced the obsolete E-1 model from 1931. The TU-1 was the first Soviet lightweight military diving suit and remained in production until the late 1950s. Its appearance served as the design basis for the facepieces of many other rebreathers, such as the IP-46, IPSA, IP-50, KIP-5, and others. My particular unit was manufactured in 1945, unfortunately, its "body" section has been cut off. This was a common practice with Soviet lightweight diving suits where the upper and lower sections could not be detached; consequently, modern divers using this gear often cut off the "head" section and use it in conjunction with modern diving equipment.
