1/200 16"/45 MKI HMS Nelson Turrets Only 1945

Highly detailed 1/200 Scale HMS Nelson Triple 16" Turret set as seen in 1945 fitted with B Turret Pom Pom and X Turret AA Tubs. These are highly detailed replacement parts for the Trumpeter kit, each turret is unique as modelled from plans and many reference photographs and information. Barrels are NOT included in this set for those wishing to use brass replacements. This set corrects the errors and inaccuracies on all the available HMS Nelson turret sets available. Many thanks to the Imperial War Mueseum for their vital photographic reference.

• Accurate armour thickness on all faces.
• Modelled with Oerlikon Tubs, Ammo Lockers (splinter shield just .3mm thick)
• Accurate sighting ports, rivets, hatches and rangefinders
• Barrels NOT included
• Coming soon in all other scales and HMS Rodney specific set

From inadequate firing trials, a mistaken theory was promulgated by the Director of Naval Ordnance (DNO) that held that a high-velocity, low-weight projectile would have superior armor penetration characteristics at large oblique angles of impact, a conclusion which was the opposite of previous findings. This theory was not substantiated by later trials, but these took place too late to affect the decision to use a lightweight APC projectile for new designs. As a result, these guns proved to be only marginally better in terms of armor penetration than the previous 15"/42 (38.1 cm) Mark I and much less satisfactory than those older guns in terms of accuracy and barrel life.

Numerous problems with liner wear, interlocks and turret roller-bearings were found and corrected in the late 1920s and early 1930s, but it wasn't until 1934 that Nelson's guns were first fired in a long, sixteen rounds per gun, all-gun sequence. A number of breakdowns occurred during this test, resulting in an energetic effort to correct the deficiencies. By 1939 the majority of the problems found had been rectified. However, these mountings were never trouble-free during the careers of Nelson and Rodney and they cannot be considered to have been a successful design. Nevertheless, it should be noted that these guns on Rodney proved to be more reliable than did the new 14" (35.6 cm) guns on HMS King George V and HMS Prince of Wales during the two battles with the German battleship Bismarck.

Constructed of a tapered inner A tube with two rear locating shoulders, A tube, full length taper wound wire, B tube, overlapping jacket and breech ring, and a shrunk collar on the rear of the A tube. A breech bush was used to attach the Welin breech block which was operated by an Asbury hydraulic mechanism. Some 29 guns were made by Elswick, Vickers, Beardmore and the Royal Gun Factory.

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.
