The 4.7"/43 (12 cm) Mark VII was a fixed-ammunition AAA gun developed late in World War I.  Only four guns were made and these did not enter service.  Performance was said to similar to that of the 4.7"/40 (12 cm) QF Mark VIII.  It had been planned to fit the "A" class Flotilla Leader HMS Codrington with these guns, but this was cancelled and she commissioned with an outfit of 4.7"/45 (12.7 cm) Mark IX guns.The 4.7"/40 (12 cm) QF Mark VIII was originally developed as an AAA weapon for the "G3" and "N3" capital ships of 1920.  When those ships were cancelled as a result of the Washington Naval Limitation Treaty, these weapons were then mounted on the Nelson class battleships and on converted carriers.  This was the largest caliber fixed-ammunition gun ever to enter service in the Royal Navy, although the rounds for these guns were lighter and shorter than the fixed rounds developed for the later 4.5" (11 cm) guns.

The fixed round for this weapon weighed a total of 74 lbs. (33.6 kg).  During service evaluation, it was found that this weapon could not maintain a high rate of fire - a necessity for an AA weapon - as the heavy round rapidly wore out the gun crews.

The Mark VII was constructed of a tapered inner A tube, A tube, full length wire, jacket and breech ring.  Used a horizontal sliding breech mechanism that was hand operated but opened automatically after firing.

The Mark VIII was constructed of a tapered inner A tube, A tube, part length wire, jacket and breech ring.  Used a horizontal sliding breech mechanism that was hand operated but opened automatically after firing.  The mounts were unusual for British guns in having a power rammer, which allowed faster firing at high elevations.  The rammer was carried by the loading tray rocking arm.  Rounds were laid in a loading tray which then was manually pushed over before the rammer could be operated and the breech closed.  Springs were used for runout.  A total of 84 guns were made.

The 4.7"/40 (12 cm) Mark X was a separate ammunition version of the 4.7" (12 cm) Mark VIII.  Only one of these guns was ever built and it was used for a few years on the submarine HMS Perseus in a 50 degree CPXV mounting.

All British 4.7" guns have an actual bore diameter of 4.724" (12 cm).

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.  Customers report that "Bestine" and "Goo Gone" also work well.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 damage to parts.
