Cette semaine, je me suis occupé de la passerelle du "Pocket Derfflinger"...
J'ai décidé de le représenter en mai 1941, avec le camouflage Baltique.
Pour cela, la proue Atlantique est en cours d'installation.
l'Amiral Lutjens aurai sans doute apprécié ce genre de compagnon supplémentaire pour son raid dans l'Atlantique avec le Bismarck et le Prinz Eugen.
Voici le SpringSharp de l'Etude 2 - "Pocket Derfflinger"
