Exact identification Aquilius, excellent, I see you are even burning midnight oil to get this in early

One of the very few Austro-hungarian floatplane designs, ordered in November 1912. The machine was constructed by the
Marinearsenal Pola and designed by Dipl.Ing. Mickl. Construction was lengthy as it first flew on September 12, 1913. The machine was not very succesfull, bad flying characteristics and an erratic 85 hp Hiero engine. It served as a trainer at Sta. Catarina and was scrapped in June 1915.
The machine had the k.u.k. Marine designation '7', being the last constructed machine from the Marinearsenal Pola. I would vote it as you name it the Marinearsenal Flugzeug 7. My point is that in later times the times was named after the designer like Mickl-Flugzeug Nr.7, which does not look very authentic to me.
After this floatplane the k.u.k. Marine turned to flying boats in which they reached a very advanced state.
