Aviatik D.I 38.63 of Flik 74/J with raised guns accessible, preferred by most pilots. The black Iron Cross on the white background painted on the wheel discs was a common decoration for the Austro-Hungarian aircraft. Kpl. Josef Marszalek crashed with this plane on 15th July 1918 due to structural wing failure.

Aviatik D.I (most likely) series 138 plane of Flik 74/J with a similar personal marking. If the marking is assumed to indicate the initial letter of a name, the fighters could belong to two people: Kpl. Karl Thomas (served at the squadron between 29th July 1918 and 22nd August 1918) or Lt. i.d.Res. Heinrich Tarangul v.Valea-Utsai (arrived at the unit on 22nd September 1918).

An Aviatik D.I with squadron markings of Flik 74/J known from a photo taken on S. Giacomo airfield awaiting an inspection, sometime in late summer or autumn 1918.

Aviatik D.I 138.43 flown by Kpl. August Staatz of Flik 74/J was forced to land near Treviso on 23rd June 1918. The personal marking (“T”) is believed to have belonged to Kpl. Karl Thomas, but he arrived at the unit on 26th July 1918.

Aviatik D.I 138.55 before and after having received new national markings in August 1918. On the latest version, the personal marking (“MIZZI”) was applied on the upper and maybe also on the under surfaces of the wide white band, while the earlier version beared it only on the sides. The aircraft was damaged by Kpl. Josef Kunz, crashing shortly after take-off on 28th August 1918.

Aviatik D.I 138.62 shows the squadron markings of Flik 72/J, a black band on the fuselage with a white number and the black wheel discs. The aircraft crashed after a fight on 29th July 1918, killing its pilot Oblt. August Dehne.

Aviatik D.I 138.119 was flown mostly by the squadron commander Oblt. Franz Cserich and Oblt. Arpad Pindter von Pindtershofen of Flik 74/J. Kpl. Adolf Wissinger safely force-landed with the plane on 19th September 1918 due to wing failure.

A pipe-smoking skull in a white band as personal marking of Kpl. Milan Soviansky on an Aviatik D.I of Flik 74/J in August 1918, considered as a plane of series 138 (or it was maybe a series of 38, for example 38.30 flown many times by Soviansky).

Aviatik D.I 238.39 of Flik 72/J was powered by 160 hp Austro-Daimler engine, which was more suitable for training than operational flying. Note the side radiators.

Aviatik D.I (Lo) 115.25 of Flik 72/J. Fwbl. Ernst Heinz crashed with the aircraft on 2nd June 1918. The series 115 fighter had a typical camouflage pattern of lozenge of flattened hexagons. Unlike the Aviatik-built aircraft, the “Bergs” produced by Lohner had camouflaged engine panels. The white number in a black band was a unit marking for identification, the exact number (“2”) is uncertain in this case (maybe “6”).

The hypothetical appearance of Phonix D.II 222.04 (or more likely 222.08) of Flik 68/J, based on the photo of the plane’s wreckage. It carried a white “X” for identification which is the only known personal marking of the squadron. Applying the unit marking (green-white wheel discs) on Phonix fighters of Flik 68/J is questionable.
