Despite not being accepted for service use a number of late World War I prototype German aircraft used the Bz.IIIb, the Benz IIIbo and the geared Benz IIIbm. The latter suffered vibration problems.Applications AEG DJ.I AEG PE Albatros D.X Albatros Dr.II Albatros W.8 Aviatik D.III Aviatik D.IV Aviatik D.V LFG Roland D.VII LFG Roland D.VIII
