These models are scaled from official US Navy drawings.  These models are not 3D-printed copies of any plastic or resin model kit's parts therefore they may be sized and shaped differently.  Some adjustment to your kit's parts or other aftermarket products such as photo-etch may be necessary for best fit.

Assembly advice: insert brass barrels or your kit's barrels into their slots and fix the barrels in place using CA.  If your kit's or brass barrels are too large, carefully drill out the trunnion slots to fit.  If your barrels are too loose, use thick, gel-type gap-filling CA glue to help fill the gap.

Among naval historians, the US Navy 5"/38 caliber gun is considered the best intermediate-caliber, dual purpose naval gun of World War II.  Lighter and squater than the earlier, heavier versions designed for battleships, aircraft carriers and cruisers, the "Mark 38" version of the twin mount was designed specifically for Sumner and Gearing class destroyers and other ships where weight was an important consideration.  This version also had differently shaped rangefinder hoods.
