    Russian Sokol KV-2 Pressurized Spacesuit Still in Use on Soyuz Flights, Developed and Manufactured by NPP Zvezda (НПП ЗВЕЗДА). A complete Sokol unflown "rescue" suit as used since 1973 by all Russian cosmonauts who fly on the Soyuz spacecraft. This lightweight full pressure suit is made to keep the wearer alive during an accidental cabin depressurization; it is not made for EVAs. In white nylon canvas with blue trim, it has an attached pressurized hood with a hinged plastic visor secured to a blue anodized aluminum clavicle flange, trussed sleeves with adjustable articulating cables in the upper arm and webbed belt lashings, a pressure gauge on the left sleeve, a mirror on the right sleeve, detachable gloves, double-V-front zip closure, lace-up crotch with triangular placket, anodized aluminum umbilical interfaces on body for electrical, air, and coolant line with attached cables and hoses, pressure equalization valve on chest, support sling wrapping from chest to back by means of webbed belts and metal clips, adjustable metrically calibrated webbed straps attached to metal rings on side seams and along crotch, pleated knees, a utility pocket on each leg, attached soled feet, and a rubberized Kapron cloth lining with a Zvezda logo patch on the chest. Until recently, this was on exhibit in a major museum. What an incredible item for display! Light wear. Very fine.

    Early Soyuz spaceflight carried no pressurized suits for use during ascent and descent. The three man crew of Soyuz 11 died during re-entry because the spacecraft depressurized. The government investigating committee recommended that pressure suits be worn during the critical portions of their missions and the NPP Zvezda company was given the contract to develop this series of suits. The Zvezda website gives the following description of the Model KV-2 suit: "The SOKOL-KV-2 is a lightweight suit with a soft integral helmet, having a visor sliding up/down. The mass of such a suit does not exceed 9-10 kg. This spacesuit is designed for the most dangerous phases of the mission in terms of cabin depressurization hazard: in the ascent phase, during docking and in the re-entry phase. In case of emergency, a cosmonaut can quickly don the spacesuit in the spacecraft without any assistance. In case of cabin depressurization, the cosmonaut in a sealed spacesuit can work in the cabin for 2 hours. When the spacesuit is not sealed, it is ventilated with cabin air. In case of spacecraft cabin depressurization, pure oxygen (instead of gas mixture) is supplied to the spacesuit from the oxygen source. This source is also used by the on-board system, which maintains the cabin gas mixture composition."

    This was my first time dealing with an auction house, and I am 100% completely impressed with Heritage. There is not an aspect of this process that I have a critique for.
