PZL. P11f "In Ruminia"

Azur-Frrom 1/72

The PZL P.11 is a Polish fighter aircraft, designed and produced in the early 1930s by Państwowe Zakłady Lotnicze.
Possessing an all-metal structure, metal-covering, and high-mounted
gull wing, the type held the distinction of being widely considered the
most advanced fighter aircraft in the world at the time of its
introduction into service.^[1]

Work on the PZL P.11 began in the 1930, based on experience with previous aircraft from the family of fighters derived from the PZL P.1. The primary individual responsible for their development was Polish aeronautical engineerZygmunt Puławski,
who has been attributed as having designed many of their innovative
features. While most of the world's air forces still operated biplanes
in the early 1930s, the P.11, like previous aircraft in the Puławski
family, used a high-mounted and aerodynamically clean gull wing that
produced less drag and provided the pilot with a superior field of view.
In August 1931, the first prototype conducted its maiden flight. The design quickly drew international attention; the general layout became commonly known as the "Polish wing" or "Puławski wing".
