PWS (Podlaska Wytwórnia Samolotów) Aircraft Designations
I've made a start on a PWS designation list - relying heavily upon listings in the Samoloty w Lotnictwie Polskim website - http://www.samolotypolskie.pl/
As usual, there are plenty of gaps to fill! Additions and corrections welcome.
PWS Aircraft Designations
PWS licensed-built a number of aircraft designs. These included a range of Potez biplane reconnaissance bomber - 35 x Potez XVA2, 150 x Potez XXVA2, and 155 (sources vary) x Potez XXVII. PWS also took over development of the Bartel BM-4h biplane trainer when the 'Samolot' (Wielkopolska Wytwórnia Samolotów) firm failed after a factory fire.
Bartel BM-4h 2-seat biplane primary trainer, licenced x 50
- BM-4h: Prototype, 1 x 120 hp DH Gipsy III 4-cyl inline
- BM-4h: Series, 1 x 120 hp Walter Junior 4 4-cyl inline

One license-built aircraft that did receive a designation of sorts was the Avia BH-33 biplane fighter. Polish examples of this Czech fighter were designation PWS-A - 'A' for Avia.
Un-numbered PWS Aircraft Designations
PWS-A - Avia BH-33 biplane fighter, licenced 1929-30, x 50
- PWS-A: Skoda Jupiter VII 9-cyl radial, span (upper) 8.9 m
-- Should have been PWS-9 but 'A' for 'Avia' used instead*

The unbuilt Stemal VII project was brought to PWS by its designer, Stefan Malinowski. The later designation style, PWS-Stemal VII, suggests that PWS also regarded this airliner concept as a potential license-built design.
PWS-Stemal VII - [Project] 1928 high-wing monoplane airliner
- Stemal VII-PWS: Init. designation, 1 crew + 4 pax
- PWS-Stemal VII: Final designation, Dural const., span 10 m
- PWS-Stemal VII: 1 x 220 hp Skoda-Wright J5 Whirlwind

Numbered PWS Aircraft Designations
Most PWS aircraft designations followed a simple numerical sequence. But there were examples of type numbers being reapplied. Most Polish sources show the designation style as PWS-xx, with the type number separated from PWS with a hyphen. Other publication use a space or a period.
Some PWS designations are shown with French-style alpha-numeric role/crew number suffixes. This seems to have been a Lotnictwo Wojska Polskiego (Polish Air Force) practice rather than a PWS style. PWS sub-type suffices are usually letters (sometimes small letters, sometimes capitals).
Designers names were sometimes acknowledged in later designations. 'M', 'U', and 'Z' designations are explained below the Numbered PWS Aircraft Designations listings.
One anomoly in the 'M' designations is the PWS-17 night fighter project which was also refered to as the PWS-17M2. But, at times, it is listed as the PWS M-2. The PWS-17M2 designation is clearly a Lotnictwo Wojska Polskiego French-style role designator. But the 'M' in M-2 is clearly _not_ a reference to inż Józef Medwecki. See Boogey's Reply #11 (below)
