Who is your first, second, third preference?
First: Iron Shipwright
Wide selection of ships from patrol craft up to and including A/C carriers in my preferred scale (1:350). All eras.
Second: Trumpeter for their choice to depart the tried and true battleship and A/C carrier lineup and venture into auxiliaries, destroyers and escorts (so they fumbled with The Sullivans - the England is supurb).
Third: Mirage for their extensive line of submarines and WWI German/post-WWI Polish destroyers.
Faded Past: Tamiya - lack of foresight and responsiveness to the customer’s wants. Trot out the SOS once more, in a new box, and hope that no one will notice.
It depends on what you are looking for. For 1/700 scale it would have to be Combrig with a massive selection (in beautifully molded resin) of subjects from the late 1890s to the present at prices that rival injection molded kits. If price is no object then White Ensign Models for 1/700 and 1/350 ships. A smaller selection of subjects (USN post WW2) but gorgeous kits are made by JAG and at very reasonable prices. NNT, WSW, Samek and Waveline all make beautiful kits in 1/700 resin. Seals Models of Japan makes extremely detailed injection molded pre-dreadnoughts. Among battleships alone there are HUNDREDS of subjects available for the modeler of virtually any period of the battleship era.
