For any modeler, but especially ship modelers, it is hard to achieve a realistic effect when gun barrels are out of round, warped or fail to have the right taper and shape; which is often the case with styrene injected or resin barrels. With smaller caliber guns and in smaller scales the barrels are often too fragile to handle. For these reasons turned metal barrels are an attractive alternative. Master Models continues to release well-priced brass barrels for the discriminating ship modeler.
Without a doubt, Dragon’s Smartkit of the Scharnhorst is a real gem with a superb level of detail thanks to its CAD designer. The gun mounts are very detailed and the molded barrels, with the slide mold technology, are quite nice in this scale, including bored muzzles. Dragon has packed the kit with a significant amount of aftermarket detail including injection molded blast bags; a nice touch given how difficult they are to make from scratch.
