This Hound-B was built in 1965 and TOC with the Polish AF with serial 6. Within a very short period it had been transferred over to the Polish Navy and given a new serial, 617. The helicopter was SOC in September 1980 and turned over to be a ground instructional airframe at Olesnica. In 1990 it was transferred to this superb museum and (at the time of the picture) recently repainted with its original serial.
