The first fighter of indigenous Polish design, the P.1
produced by the Paristwowe Zaklady Lotnicze (P.Z.L.),
or National Aviation Establishment, embodied several
technical innovations. Designed by Zygmunt Pulawski,
the P.1 was of all-metal construction, its most novel
feature being the "gulling" into the fuselage of the
centre section of the high wing, thus eliminating the
normal cabane. This both reduced drag and improved
the forward view for the pilot. Powered by a 12-cylinder
water-cooled Hispano-Suiza 12 Lb Vee-type engine
affording 630hp for take-off, the first prototype, the
P.1/I, was flown on 25 September 1929. Armament comprised
two 7.7mm Vickers machine guns. The second
prototype, the P.1/II, featured a repositioned radiator
bath and redesigned vertical tail surfaces, and joined
the test programme in March 1930. Further development
was discontinued in favour of radial-engined
variants, as the Polish air arm, the Lotnictwo Wojskowe, was biased against liquid-cooled engines.

it's "Państwowe Zakłady Lotnicze" (Państwowe meaning national), not "Paristwowe".
