1/350 Scale HMS Agincourt 12" BL MKXIII Guns x7 as seen in 1916. These are highly detailed parts modelled from original plans and using many reference photographs. These have been created to replace the inaccurate (and under detailed) Turrets found in the Iron ShipWrights 1/350 HMS Agincourt Resin Kit. This set contains 2 different types of Turret 4x with 9ft Rangefinder (Monday, Thursday, Friday and Sunday Turrets) and 3x with 15ft Rangefinder (Tuesday, Wednesday and Saturday Turrets).
- Accurate armour thickness and dimensions from original plans
- Hex Nuts, Rivets, Sighting Ports and Hatches
- Barrels are printed separately and can be angled as desired to a maximum of 14º
These were Elswick Pattern W guns developed for the Brazilian Navy for installation on the battleship Rio de Janeiro
. They were an improved version of the Elswick 12"/45 (30.5 cm) Pattern L guns
used to arm the Brazilian battleships Minas Gerais
and Sao Paulo
. The design of the Mark XIII guns was very similar to that for the 12"/45 (30.5 cm) Mark X guns
used on HMS Dreadnought, but they were not interchangeable with them.
Rio de Janeiro
was a very unusual design in that she had seven twin turrets fitted, the most of any dreadnought ever built. The turrets themselves were developed by Elswick as a more or less private venture and their design was then carried over to the 14" (35 cm) twin turrets
developed for HMS Canada (ex-Almirante Latorre
Rio de Janeiro
was taken over by the British at the start of World War I and renamed HMS Agincourt.
It is noted that when she was first taken over, Agincourt lacked sub-caliber guns and as a result firing practices were restricted and her battle efficiency was reduced. There were many problems with the newly designed hydraulic loading gear during her first firing trials and the electric igniters failed to function at the first salvo, requiring use of the back-up percussion method. There were also problems with the shells themselves, which showed an alarming tendency to break up in flight. This was attributed to the age of the shells, some of which were stenciled "Repaired in 1892." There were also design problems with the guns, such as the butt strap joining A and B tube which was thought to impede the projectiles as they passed and to a poorly designed forcing cone, which was thought to cause the shells to not seat properly.
At Jutland (Skagerrak) she was in action for a short period and where it was reported that the sheet of flame generated when she fired her guns "was big enough to create the impression that a battle cruiser had blown up; it was awe inspiring." Agincourt fired a total of 144 rounds from her 12" (30.5 cm) guns during this battle, her only combat engagement.
HMS Agincourt is notable for having had Dr. Oscar Parkes, author of "British Battleships: 1860 - 1950," as a crewmember.
Constructed of a heavy inner A tube in three parts, full length wire, B tube and jacket along with breech bush, screwed on ring and Welin breech block. A total of fourteen guns were made and a further seven to a modified design which had a one-piece A tube and tapered inner A tube.
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.
