Well finally a manufacturer has stepped in and made a replacement set. Loose Cannon Productions is relatively new on the scene, but their kits are very detailed and accurate. They have recently started making some of their accessories available separately. One of these is a completely new Dual 5 inch gun turret. One of the drawbacks to injection molding is that parts have to be slightly tapered in order to release from the mold without distorting. So even the most accurate of the plastic turrets out there have a slight draft to them. This is not a problem with a resin mold as it is flexible and the result is that these sides are vertical and flat. There is also cast on sighting hoods and tapered gun barrels with molded on hoods.
