More than that the Russian Civil War wasn’t even over and Poland was formed by the Central Powers from the crumbling Russian Empire of which Poland had been apart of since the 1870s.
1918-1922 was a period where four empires, German, Austria-Hungary, Russian, and Ottoman all disintegrated. Many within the ashes were left to the whims of the British and the French’s geopolitical goals.
Considering those look like Zeros this looks pretty WW2. Anti-Imperial Japan maybe.
The mixed landing gear bothers me though.
