There is a fantastic new book on Austrian-Hungarian artillery from 1867 to 1918.
Its: C Ortner "Die österreichische-ungarische Artillerie von 1867 bis 1918. Technik, Organisation und Kampverfahren" (Verlag Militaria) (www.militaria.at)
637 pages on all with lots of info on all artillery pieces (even experimental ones) and some info on captured ones. Also info on organisation and tactical use.
All of Verlag's books are amazing. My favorites are the two-volume set on French troops. In the U.S., Bill Combs' AGM Ohio is the authorized distributor. His link to his book list is:

I didn't see the Austrian Artillery volume on the list, but I know he has it (bought my copy from him). You may want to inquire if he still has it in stock.
