Speculation, I say. Well, now wouldn't a couple few nice seaplanes give realism to those lonely Seefrosta units. A Friedrichshafen FF-49 or Albatros W-4, perhaps a nice Felixstowe here and there, would add a bit of spice to things, what!
"War: first, one hopes to win; then one expects the enemy to lose;
then, one is satisfied that he too is suffering; in the end,
one is surprised that everyone has lost."
-Karl Kraus, Die Fackel, October 19, 1917
