There are a number of historical battleships in the Marketplace, but there's a paucity of very early types so I'm working up an add-on for for my Massena pre-dreadnought.  The variations won't represent an actual historical ship but will reflect many of the features of battleships that existed in the early 20th century.  Here are some of the variations:

Dazzle camouflage

Tripod masts

Lattice or cage masts - these, actually a mathematical hyperboloid construction, were surprisingly easy to model.

Here is the aft lattice mast.

The Massena product has essentially static smaller (3-pounder) gun props.  The variations will include semi-rigged compound 3-pounder and 1-pounder gun props.  These will be provided as smart props sets, but also as extras that can be used anywhere or in any scene.

Building the lattice variation for the forward tower.  It will include a small gun platform.

This is the lattice or cage mast variation;

And with dazzle camouflage.

Kitting up.
