I'm resurrecting this thread to bring you a drawing of an interesting Italian design that never went beyond the blueprints.
The Fiat Cr.44 was intended to be a high speed fighter bomber, but due to its size, 14.2m long and 15.2 of wingspan, it would've been more like a bomber-fighter (kinda like the British Mosquito in spite of the obvious differences)
Italy, Fiat Cr.44:
Last but not least: Thanks to Eswube for his review on this design.
