Can anyone identify the fighter here in this picture taken from a Dornier-do17?
It's a Hurricane. No Spitfire of any Mark had a radiator under the fuselage, whereas every Hurricane, from the prototype to the "Last of the Many" did. And that is NOT a carburetor (carburettor in British English) air inlet. Re the comment about the canopy, Mark I Spits had a narrow canopy. No framed greenhouse, but not blown out at the sides either. The earliest Mark I Spits had a canopy that effectively was just an extension of the windscreen. Later ones had a bulged top for more head clearance, but still had flat sides. Later Marks featured the "blown" canopy that was bulged on the sides as well.
