History
The B-series was the first production model of the 109. The V-4 to V-13 prototypes served as the pre-production B-0 series. The B-series was powered by the Jumo 210 A, B, D, Da and G engines. In 1937 45 B-series aircraft were shipped to Spain for operational trials in the Spanish Civil War.
B-0 (1937)
These were the 10 prototypes V-4 to V-13. Some of these aircraft were armed with 3 MG 17’s. The V-11 and V-12 were equipped with the DB600 engine.
B-1 (1937)
The B-1 was basically similar to the B-0. It was armed with 2 MG 17 machine guns.
B-2 (1937)
The B-2 was fitted with a metal variable pitch VDM prop. Originally the B-2 was fitted with a third MG 17 firing through the propeller hub. This was often deleted in the field however as it did not function properly.
