Soyuz 7K=OK spacecraft Descent Module Hydrogen Peroxide Yaw Thruster for attitude control, measuring approximately 11.5 x 6.5 x 4.5, engraved on the central bracket in red,  The nozzle measures 2 inches in diameter and is engraved above. The thruster is set on a metal display mount with a base.  In fine condition.

The Soyuz Descent Module used eight reaction control micro-jets as part of the Entry Actuators System, with two for pitch, two for yaw, and four for roll; the pitch and yaw thrusters provided about 8 kilogram-force while the roll thrusters provide about 15 kilogram-force. Peroxide is catalyzed in the system, breaking down into water and oxygen that escapes at high speed to create thrust.
