I found this old store display. The size of this diorama is a about 140 x 85 x 50 cm.
The pirate ship is placed on a mechanism that allows it to swing stern/bow and port/starboard when the electrical plug (not shown in the photos) is attacked.
The display includes:
3466 – Small Castle
7055 – Three Palm Trees
3795 – Harbour Guard
3792 – Pirate with Rowboat
3750 – Pirate Ship
I hope that this details are useful.
