2nd picture:
This one shows the bow of the 5135-ship.
It is clear that the opening in the front-deck, to access the front guns on the 3940/3286, has been covered on the 5135.
If the cover is removable, or if it is fixed and part of the deckmould, is not known.
A Playmobil-employee at the Toyfair has confirmed the guns below deck are "fakes".
