One of the cache of German props we recovered from an attic in Germany which is now cleaned and conserved.  

This Heine propeller is constructed of two laminations of mahogany and several of ash, which gives the well-known striped effect.  The prop is in conserved condition.  The original varnish has been lightly cut back and a new layer of French polish added.  

The prop is made for the NAG 185hp engine which was a licence built version of the Conrad CIII, made by National Automobil-Gesellschaft AG of Berlin.  Sufficient engines were produced for two hundred of the DFW CVc aircraft.  Most DFW CV’s were fitted with 200 hp or 220 hp Benz engines.  It is unusual to be able to attribute a German prop to a specific type of aircraft.  The excellent DFW CV (built by the Deutsche Flugzeugwerke of Leipzig) first appeared in 1916 and was used as a recce aircraft, although eventually it was used for every kind of duty.  

By 1917 over 1000 were in use on the Western front.  DFW was unable to produce them in sufficient numbers and the aircraft was also built by Aviatik, Halberstadt and LVG.  More were built than any other German design in WW1.
