PZL P.50 Jastrzab

Intended as a successor in Lotnictwo Wojskowe service to the P.11, the P.50 Jastrzab (Hawk) was designed under the leadership of Wsiewolod Jakimiuk. The first of two prototypes, the P.50/I, was flown in February 1939 with an 840hp Bristol Mercury VIII nine-cylinder radial. Of all-metal stressed-skin monocoque construction, the P.50 was armed with four wing-mounted 7.92mm Wz 36 machine guns. The Mercury-engined model was referred to as the Jastrzab A, an initial batch of 30 of this version being under construction at the time of the German invasion. The second prototype, the P. 50/II, was intended to serve as a development aircraft for the more advanced Jastrzab II. This featured a revised rear fuselage, armament augmented by two 20mm cannon and pilot armour, the engine being a 1375hp Bristol Hercules to be replaced in the series model by the 1200hp P.Z.L. Waran radial. The P.50/II was still awaiting its power plant at the time of the German assault. The first pre-series Jastrzab A was to be fitted with an 870hp Gnome-Rhone 14Kirs as a development aircraft for the Jastrzab B, and this was almost ready for flight test in September 1939.

I remember reading somewhere that the prototype of the A version was shot down by Polish AAA gunners, because they thought it was a German aircraft! Is there any truth in this?

Really P-50/1 can fly only 430-440km/h. 500km/h was a planned speed

HOW CAN I FIND UNDER SCALE AND CROSS SECTIONS PLANS FOR PZL 50 JASTRZAB PROTOTYPES II AND III?

This plane resembles an amalgamation of the Bloch 151 and the Seversky P-35.

The Polish air force may have had a fighting chance had this fighter been in service in Sept. '39. It's reminiscent of the Brewster Buffalo, an American fighter used effectively by the Finns against the Soviet Union, and less so by the U.S.M.C. against the Japanese.
The PZL-50 would've shredded the Dorniers, Heinkels, and Stukas without heavy Bf-109 escort.
