In contrast to the Zeppelins, the Parsevals were non-rigid or semi-rigid airships, with little or no stiffening structure inside the fabric envelope.
PL 26 was a semirigid airship whose maiden flight was on 1915-10-26, but it had an accident upon landing and was destroyed in a fire, with no casualties.
On 1930-05-21 PN 29 acquired the Swedish call-sign "SE-ACG Sidenhuset", after the then well-known ladies boutique from Stockholm.
Sidenhuset's task was to make advertising flights over the 1930 Stockholm Exhibition (Stockholmsutställningen).
The manufacturer arrived and it was decided to fly the ship back to Germany for repairs.
