The PWS 33 advanced trainer is very similar in appearance to the British Reid&Sigrist RS1 Snargasher twin-engined,three seat advanced trainer prototype first flown in early 1939.It did not go into production though its performance and handling was reported to be good in both normal and aerobatic flight when it was tested at the Martlesham Heath Test Establishment.The British aircraft had a fixed undercarriage.Did the PWS 33 have a retractable undercarriage?In the photograph the three Polish Air Force airmen are standing in front of the main wheels and it is impossible to see if the undercarriage is a fixed or retractable type.

The plane was built as a trainer for polish multirole twin engine fighter PZL P.38 Wilk (Wolf) When the P.38 project was screpped the P.W.S. 33 was not needed anymore.
Also the plane was named Wyżeł (pointer)
