Hi Stig,
You can see the first volume in the series here:
https://www.amazon.co.uk/Austro-Hung...s%2C544&sr=8-1
As you'll note much easier on the pocket than some Aeronaut publications. I found this volume useful as it has tables for known aircraft serials for the machines used by each of the Fliks,also the usual profiles,photos and text (more of the latter than in many of the volumes dealing with German aircraft).
A future volume including Flik 63/J would be very welcome from both a pictorial and an informational point of view.But what would be really great is volumes covering the non fighter Fliks.
Regards,
Clint
