Historical Information
This weapon entered service on the dreadnought HMS Bellerophon and later replaced some of the 4"(10.2 cm) Mark I and Mark III guns used on older ships.

These weapons were installed in both casemates and in single open mounts on British dreadnoughts. The open mounts were installed without shields but some ships had these added after 1917. In 1918 a HA mounting using a reduced charge was introduced and most capital ships had one or two of these installed on a main caliber turret for anti-aircraft purposes.

During World War II these weapons were used on many minor warships and a considerable number were used as coastal artillery.

Mark VII was constructed of inner A and A tubes, wire wound, B tube to the muzzle with jacket, breech ring and breech bush screwed into the A tube. Used a Welin breech block with "pure couple" breech mechanism. Cannelured rings for reducing "steel choke" were placed between the shoulders of the A and inner A tubes. Mark VII* was a single gun made by Beardmore with a different construction. Mark VII** were fifteen guns with no inner A tube and with the B tube and jacket being combined.

Firing could be either percussion or electrical. A total of 600 of these weapons were produced, of which 482 still remained in 1939.

          
Cleaning Information
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.
