Parseval
"The Parsevals were 22 airships built between 1909 and 1919 by the Luft-Fahrzeug-Gesellschaft (LFG) following the design of August von Parseval."[1]
But it is the Parseval which is regarded as the finest type of airship flying the German flag. This vessel is the product of slow evolution, for it is admitted to be a power-driven balloon. Even the broad lines of the latter are preserved, the shape being that of a cylinder with rounded ends. It is the direct outcome of the 'Drachen-Balloon,' perfected by Parseval and Siegsfeld, the captive balloon which is an indispensable part of the German military equipment.[2]
Howlett, 2021 clearly states that the British side also used Parseval airships, at least "type No. 4", to monitor its coasts. They must have been made in Britain. Details to come. The en.wp w:List of Parseval airships article does not appear to acknowledge any use of them outside Germany. Need to reconcile.
