Product Description
This is a highly detailed set of 4 1/350 BL Single 4" 50 Cal guns.
These guns were first used as secondary guns on the Arkansas class monitors and then on nearly all of the "Flush-Deck" destroyers as well as on many submarines. Well-liked on the latter ships, as its light weight made it easy to handle, an important factor on a small ship.
Many individual Mark 9 guns were supplied to the British during World War II as part of Lend-Lease. In addition, these guns armed numerous ex-USN warships transferred to Britain, including destroyers, submarines, escort carriers and DEMS. In total 424 guns were transferred to the UK, mainly Mark 9. The USN also sent 60 guns for Dutch DEMS and 21 guns for Norwegian vessels. By the end of the war, most Lend-Lease destroyers were reduced to only one 4"/50 (10.2 cm) gun and four escort carriers were rearmed with British 4"/45 (10.2 cm) Mark V guns. In British service these USN guns had a poor reputation as they were prone to coppering and steel choke problems. Vickers was asked to provide special liners designed to work with USN ammunition for these guns and for the Mark XVI*, but it was found that this raised the barrel pressure of the latter gun to unacceptable levels.
Mark 7 was constructed of A tube, jacket, hoop locking ring and liner with a screw breech. Mark 8 was a simplified design consisting of a gun tube and jacket. Mark 9 was a light weight design for destroyers and submarines and was originally built with A tube and full length jacket with a muzzle swell and used a Smith-Asbury type side swing breech mechanism with a Welin block. Later mods were of monobloc construction and used chromium plating to increase life. Mark 10 had a vertically sliding breech block and was intended for anti-aircraft use, but this Mark does not appear to have been put into service.
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.
