O.Thetford, P.Gray German Aircraft of the First World War (Putnam)

Halberstadt B
   Other than in its undercarriage, there was little to distinguish the Halberstadt B from its contemporary B types. It is doubtful if more than one or two were built and unlikely that they saw any service other than in a training capacity. Engine, 80 h.p. Oberursel U O.

Halberstadt B-Type

  The Halberstadt B-type used a rectangular, tubular steel fuselage derived from the Fokker M 8 fuselage. To that a biplane wing cellule with 3 1/2 bay bracing was added, although no cabane struts were fitted. The engine was an 80 hp Uberursel U.O seven-cylinder rotary.
  The wings were of rectangular planform but the ailerons extended back beyond the wing's trailing edge. The main undercarriage had two pairs of dual wheels attached to U-shaped struts. No fixed fin was fitted; however, the rudder was large. The tailplane had fixed horizontal stabilizers and a movable elevator.
  The aircraft had features that previewed later B-types and D-types.
  At least two examples were built at the end of 1914; work numbers 117 and 118 are known [Hindenburg I and II).
