Thank you for the information.
After looking over the map at http://www.kuk-wehrmacht.de/regiment/img/oegarnkart1898.jpg
I have a couple of questions for clarity:
The legend titled "K. ung. Landwehr" is for the Royal Hungarian Army?
Legend "K. k. Landwehr" is Imperial Royal Army (Austria)?
The rest of the legend is for the Imperial & Royal AH Army (joint)?
Why do think 34/2 and 85/1.3 are Train versus Infanteria-Regiment or detachiertes Batallion? In either case I assume thse would by k.u.k?
For the Royal Hungarian Army, I understand the reasoning for 9/4, but why do suggest 15/3?
From my understanding Hungarian Army records post-1867 have been lost. I'm assuming I would not be able to find records if my grandfather served in the k.u.?
Again thank you for take the time to answer my questions.
