Comments: This is a very early WW1 era German propeller, probably from 1912 or 1913, manufactured by Integral Propeller (Deutsche Integrale Luftschraube) and used on the LVG B.I ("Doppledecker") with a 100 HP Mercedes Benz engine. The design is typical of Lucien Chauviere, with a curved leading edge and straight trailing edge. Although Chauviere was a Parisien his Integral Propeller company had subsidiaries in England, Germany, Austria, and Russia. This propeller is in rare original condition and shows evidence of having been mounted and used in service during WW1.
The LVG B.I was developed in 1912 as a reconncaissance aircraft and by 1915 was replaced with the B.II version using a 120 HP Mercedes engine.
