Messerschmitt Bf-109 C-1 WWII German fighter

The short-lived Bf 109C ("Caesar") was powered by a 700 PS Jumo 210G engine with direct fuel injection. Another important change was a strengthened wing, now carrying two more machine guns giving four MG 17 in total. The C-0 were pre-production aircraft, the C-1 was the production version, the C-2 an experimental version with an engine-mounted machine gun. The C-3 was planned with 20 mm MG FF cannons replacing the two MG 17 machine guns in the wings but its not known how many C-3 (if any) were built or converted. The C-4 was planned to have an engine mounted MG FF, but the variant was not produced.
