Hello John MacG, Three Albatros D.IIIs of Series 53 served with an Austro-Hungarian provisional fighter unit known as Flieger Detachment Hptm. Karl Nikitsch
based at Kezdi-Vasarhely on the Romanian Front from early July to mid-September 1917. The unit also had two Hansa-Brandenburg D.Is (known as KDs). Six of eight enemy aircraft fell to Albatros during its brief existence.
Please visit my website http://www.warchron.com
which addresses the Russian and Romanian Fronts in WWI. The Forum section has recently been expanded to include a variety of new aviation threads. You will soon find coverage of the Austro-Hungarians there. Cheers, agblume
