PW-5 and PW-6 production by PZL Swidnik has been transferred in June
2005 to ZS Jezow (also known as "The glider factory"). This is the
old Grünau factory where Edmund Schneider produced the SG-38 and
Grünau Baby before and during WWII. The former German town Grünau is
now Polish and is called Jezow Sudecki. ZS Jezow is a former part of
the PZL conglomerate, and specialised until now in the maintenance and
repair of PZL gliders.
