Here are some images of Hobbycraft's 1/48 scale BF 109 B.
The first Bf 109 in serial production, the Bf 109B , was fitted with the 670 PS (661 hp, 493 kW) Jumo 210D engine driving a two-bladed fixed-pitch propeller. During the B-1 production run a variable pitch propeller was introduced and often retrofitted to older aircraft; these were then unofficially known as B-2s. Both versions saw combat with the Legion Condor during the Spanish Civil War, although it was apparent that the armament was still inadequate. Several aircraft were produced with an engine-mounted machine gun but it was very unreliable, most likely because of engine vibrations and overheating. Thus the Bf 109 V8 was constructed to test the fitting of two more machine guns in the wings; however, results showed that the wing needed strengthening. In the following V9 prototype both wing guns were replaced by 20 mm MG FF cannons.
A total of 341 Bf 109B of all versions were built by Messerschmitt, Fieseler, and Erla.
The short-lived Bf 109C was powered by a 700 PS (690 hp, 515 kW) Jumo 210G engine with direct fuel injection. Another important change was a strengthened wing, now carrying two more machine guns giving four 7.92 mm (.312 in) MG 17s in total. The C-0 were pre-production aircraft, the C-1 was the production version, and the C-2 was an experimental version with an engine-mounted machine gun. The C-3 was planned with 20 mm MG FF cannons replacing the two MG 17s in the wings, but it is not known how many C-3 (if any) were built or converted. The C-4 was planned to have an engine-mounted Motorkanone MG FF, but the variant was not produced.
