Warships, castles of steel.
There's a couple of questions that you need to ask your staff.
1. Size of ship.
2. Navy.
3. Era.
4. Media.
So assuming that Arizona BB-39 is a point of interst, we can assume-
USN
20th century.
The first suggests a smaller scale. Ship models take years if large to finish.
1/700 scale is a good size for capital ships like battleships and aircraft carriers.
That in turn steers you towards the asian companies. Aoshima, Pit Road, Dragon, a very few Tamiya.
The second makes kits in the smaller scales hard to find, and limited in the larger scales; for french, italian, chinese, spanish or other smaller navies difficult to find.
The third basically differentiates steel from sail. That is entirely up to you. Plastic steel navy ships, resin for that matter (see next entry), are easy to find, depending on scale and navy as touched on above.
Fourth, media. Plastic kits are limited in selection as there is a need to sell several thousand kits of any ship to make them profitable. Resin kits cut that number significantly.
Suggest a subject and I would be happy to let you focus a little.
