First products released and for sale right now are in 1/350 scale:
Forward Superstructure: http://shpws.me/Q9Xs
Coming next will be the 01 level (former boat deck and casemates), the aft fire control tower, and a dedicated set of fire control directors for re-built, pre-war battleships (two Mk.37 directors and one Mk.34 director). 14" turrets, 5"/38 mounts, and Pennsylvania's aft vents are already available.
And for the modeler who enjoys the occasional wingy-thing, 1/32 scale hollow Packard-built Merlin engine exhausts are available for your P-51 Mustang kits. The design is optimized for the new Revell P-51D-5 kit.
A set of P-51 Mustang exhausts is also available in 1/24 scale. They can help improve the otherwise excellent classic Airfix/Heller/MPC kit's Merlin engine: http://shpws.me/Q9tO
