Just a guess,
The USN mk48 (as opposed to v48) turret was the twin 5inch 38cal turret fitted to Sumner and Gearing class USN WW2 Destroyers.
The scale seems to big though for a destroyer,looks like a cruiser or Battleship turret (four decks deep ),Will keep looking.

Have a look here,
GUN MOUNT AND TURRET CATALOG - ORDNANCE PAMPHLET 1112. USN WW2 document re naval turrets.
Could not find this turret though,maybe a prototype design?
The mk48 was a lighter version of the mk38 twin 5 inch I believe but i don't think it,s the one..
