This set of finely turned stainless steel and brass gun barrels for is designed for the new Academy USS Indianapolis kit. It does not include a styrene turret face, as is included in the set designed for the Trumpeter kit, but could undoubtedly be used to augment the Trumpeter San Francisco class cruisers as well.
Each of the 8” barrels are slightly tapered with very finely defined segmentations. The short stubs at the end of the barrel allows for easy insertion into the kit’s turret face. Although the barrel openings are not as pronounced as compared to other Master barrel sets (or the kit’s barrels), these barrels are noticeably longer, more even and, no doubt, more accurate than the kit parts. A couple of my kit’s barrel ends were noticeably uneven. That’s not an issue with the Master barrels.
