Scale: 1/144    

Set includes 4 mounts (turrets) with barrels (2 "double knuckle" and 2 "single-knuckle").
 
Among naval historians, the US Navy 5"/38 caliber cannon is considered the best intermediate-caliber, dual purpose naval gun of World War II.  These models represent the four steel-top 5"/38 cal. Mk.30 mounts fit to Benson class and Gleaves class destroyers before 1944.  Please consult your references to know if this type is correct for your model.

Two of the mounts in this set represent the "Double Knuckle" configuration, which had a reinforced roof with two "bumps", called "knuckles", that resisted blast from another 5-inch turret firing overhead.  The other two mounts in this set represent the "Single Knuckle" configuration, which did not have roof reinforcement. 
 
Of the four 5-inch/38 Mk.30 single mounts normally fit to a Sims, Benson or Gleaves class destroyer, two "Double Knuckle" heavyweight mounts were carried, one in the foremost position and one in the aft most position on the main deck, known there as "Mount 51" and "Mount 54".  The other two mounts were "Single Knuckle" mounts, positioned above deckhouses, and were known as "Mount 52" and "Mount 53".
 
Compared to the later versions, the early versions, reproduced here, appeared sometime before 1944, had a different arrangement of stiffeners on the front of the gunhouse, fewer fasteners on access hatches, differently shaped shell ejection chute, and a differently positioned equipment box.
