Navis Neptun 1/1250 L10 Deutschland, Zeppelin Airship ZIX, LZ25, of 1914
This airship was designed as a civilian airship but was sister to the first successful naval airship, L3 (LZ24) and may have been undergoing conversion to a naval airship when she was destroyed in the hangar in a bombing raid on 8th October 1914.
Other similar "m-type" airships were: LZ27-35 & LZ37, most of which served with the German Navy from 1914-16 as scouts and bombers.
