Queen Elizabeth Class 6"/45 (15.2 cm) BL Mark XII Gun with Shield (Deck Mounted) x2. This is a highly detailed part modelled from original plans and using many reference photographs. These are the 2 Deck Mounted 6" Guns that were removed from casemates alongside Turret Y and placed on the weatherdeck. These had a larger curved shield than that carried on the A, B, C, D, E Class Cruisers.

First carried by the cruiser HMS Birmingham in 1914, this weapon was used as the secondary gun on the Queen Elizabeth and Royal Sovereign battleship classes and as the main gun on all cruisers built during World War I. These guns were 5 calibers shorter than the previous 50 caliber guns in order to make them easier to work on small cruisers. The lively nature of those ships had made the 50 caliber guns unwieldy and hard to manage. During World War II some AMCs and gunboats were fitted with guns removed from scrapped ships.Constructed of inner A tube, A tube, full length wire, full length jacket, breech ring and breech bush which screwed into the A tube. Used a hand-worked Welin breech-block. Mark XIIA had a modified chamber with parallel front end, while the Mark XIIB had a modified chamber with a bore of 5.985" (15.202 cm) in an effort to improve accuracy. Where practical, it was preferred not to mix Mark XIIB with Mark XII or XIIA, but all guns were interchangeable. A total of 463 guns were manufactured for the Royal Navy, of which 431 remained in service as of 1939. Although none of these guns were specifically manufactured for the Army, many were transferred from the Navy during World War II for use in emergency coastal defense batteries.
Actual bore length was 45.11 calibers.
Some part cleanup will be necessary. The 3D printing process uses a waxy substance to support certain part features during the printing process. Although the parts are cleaned by Shapeways, some waxy residue may remain. It can be safely removed with water and a mild aqueous detergent like "Simple Green" using an old, soft toothbrush, Q-tips or pipe cleaners. During the printing process, liquid resin is cured by ultraviolet light. Microscopic bits of resin may remain uncured.
Let your parts sit in direct sunlight for a few hours to fully cure the resin.
Water-based acrylic paints meant for plastics is strongly recommended.
Other paints, especially enamels, may not cure on Frosted Detail 3D-printed plastics.
Use dedicated model sprue cutters to remove parts to minimise the risk of damage to parts.
