The Five-Inch/51 gun was the was the standard secondary gun for the USN battleship designs prior to World War Two. It was also mounted on the following Carrier
classes:  
Langley (CV-1), Long Island (AVG-1), Bogue (CVE-9), Sangamon (CVE-26) and Charger (CVE-30); Destroyers: Hatfield (D-231), Brooks (D-232), Gilmer
(D-233),
Fox (D-234) and Kane (D-235) and submaries: Barracuda (SS-163), Bonita (SS-164) and "T" (SS-198) class. The label on the photographs is wrong in that
the 5-Inch/51 was for surface action only, as the 5-Inch/25 was the prewar DP gun. The USMC 5-Inch gun battery at Wake Island used this gun, as it was used for
shore batteries. The gun could also be found on USCG cutters and merchant ships.
3D Model Parts provides twelve of these mounts with set U730 in 1:700 scale. Each
gun mount has two pieces with the gun and separate mount.
