3. Addition of hot air gun heating system with corresponding vents in the lower wings, (from January, 1939).
This feature was retrofitted to existing aircraft.
4. The first and third machine guns (from the fuselage) remained
staggered on aircraft that received the retrograde heating
systems, and so their barrels protruded slightly forward
of the leading edge of the wing.
5. In aircraft manufactured with the hot air gun heating system,
the gun muzzles were within the leading edge of the wing.
6. A G.42B gun camera was installed in the leading edge
of the wing.
