Perhaps the name never caught on - or was simply forgotten. Ladislas D'Orcy has it listed as such:
D'Orcy's Airship Manual - Stagl & Mannsbarth, Vienna
It appears the gondola was originally enclosed (a photograph taken on 10 Juni 1911 shows this clearly), then at some point in time this was painted with a large AUSTRIA spanning the arch. The photo in my above post is the only one I know of that shows this moniker. Soon after - as photographed 2 November 1911 at Wiener Neustadt - the fabric covering was dispensed with and only the ballonet tubes running the length of the open framework are to be seen. Or, just as likely I suppose, the canvases were reattached and lettered later on.
The apparatus must have been quite complicated to operate in that it had lifting planes, a rudder, swiveling propellers fore and aft, and four(!) ballonets. I've read it was difficult to control (turn?) and for that reason not accepted by the military. However I don't entirely trust the source of this opinion and the Stagl-Mannsbarth's accomplished record tends to otherwise put it in the column of successes. I'm curious- did it in fact ever take part in acceptance trials or was it always intended to remain an excursion sight-seeing airship?
D'Orcy notes
Austria's best endurance as 8 1/4 hrs. This was on October 14, 1911 - a flight made with 8 people on board.
