The Republic P-44
"After being reorganized as Republic Aviation, an order was taken from Sweden for the EP1-106, essentially a development of the P-35 with 20 inches added to the length of the fuselage. There were other minor changes, not easily spotted. Interesting enough,
the Italian's thought highly enough of the P-35/EP1-106 to blatantly copy it as the Reggiane Re.2000. The Italians improved the landing gear, designing a flush folding system. A reworked greenhouse and a different engine installation do little to hide the aircraft's ancestry."
I had not heard that before. I do see the similarity though.
