Product Description

This is a highly detailed 1/350 scale RN 8 Inch MKVII set of turrets for the HMS Suffolk. These are also suitable for the HMAS Canberra, HMAS Australia, HMAS Shropshire, HMS Cumberland, HMS Cornwall, HMS Devonshire and HMS Kent.
  • Highly detailed models based on plans and historical reference for the most accurate 8 Inch MKVIII turrets anywhere, these are the unmodified shorter version with wedge shaped vent on underside (MKI)
  • Barrels are printed in placewith 3º elevation (elevations can be requested)
  • Also Available without barrels
  • Sighting hoods open, also available closed
  • Please see my other listings as I will be producing this set in other scales and for specific ships.

This weapon was designed for Britain's Treaty Cruisers of the 1920s.  Similar to other cruisers of that era, the mountings for these weapons were given a high maximum elevation in order to provide an anti-aircraft capability.  However, the training and elevation gear was inefficient and both the elevation and training rates were too slow to allow these mountings to be useful in that role.The complex nature of the early versions of these mountings, the Mark I and Mark I*, gave trouble for a number of years.  Considerable attention was paid to these faults, especially in 1927 and 1928, before these ships were accepted into service.  After the initial trials, the training and elevation rates were reduced prior to commissioning and reduced still further during the 1930s in an effort to improve the operational performance of the turrets.

On 26 July 1929, one of these guns on HMS Devonshire suffered a catastrophic breech failure at the first salvo during a practice firing.  One shell and a number of cordite bags were ignited, blowing off the roof of "X" turret and killing one officer and seventeen crewmen.

Most of the problems seem to have been satisfactorily resolved prior to the start of World War II, but HMS London reported as late as June 1938 that "one would wish that the 8in mountings and torpedoes would behave as they should.  The prolonged firing of 20 rounds per gun from London was a disappointment on the material side."

The later Mark II mountings appear to have been much more reliable, with the first gun trials for HMS York in February 1930 being so successful that they took only four hours to complete.  As a weight saving measure, the Mark II* version of this mounting, used only on HMS Exeter, had a significantly reduced maximum elevation.

The original design was A tube, wire, B tube, overlapping jacket, breech ring and breech-bush and these guns were designated as Mark VIII* upon completion.  Owing to troubles with the A tube forging, an inner A tube was added to half of the wire wound guns.  After relining with a tapered inner A tube, guns were then designated as Mark VIII.  Two prototypes and the last 26 guns built did not use wire and were designated as Mark VIII**.  All guns used a Welin breech-block with hydraulic or hand worked Asbury mechanism and were interchangeable with each other.  A total of 168 guns were produced, including the two prototypes built without wire.

Six Mark VIII** guns were used as coastal artillery in the Dover - Folkestone area during World War II.  These were in single mountings capable of +70 degree elevation.

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 the risk of damage to parts.
