Historical Data
First used on the "27-knot" destroyers of the 1890s. Many small warships still carried these old guns during World War II and they were also used in coastal defense batteries.

The Mark I was a fairly complicated design of A tube, B tube, jacket and C hoop shrunk over the B tube/jacket join. The Mark II was a First World War gun with a combined B tube and jacket while the Mark V was produced during the Second World War and had a monobloc barrel. Some 4,737 Mark I and IIs were built along with an additional 3,494 Mark Vs. Canada also built over 1,000 of these weapons, which were referred to as the "Ogden 3-inch" as they were manufactured at the Canadian Pacific Railway's Ogden shops in Calgary.

The Japanese guns were originally purchased directly from Elswick and Vickers but later ones were license-built copies. These guns were similar to or virtually identical to the British Mark I. Used as anti-torpedo boat guns on larger warships. Redesignated as 41st Year Type on 25 December 1908. Redesignated in centimeters on 5 October 1917. Although finally classified as 8 cm, the bore remained 3.0" (7.62 cm).

Early Italian guns were purchased from Elswick. Nearly all of the later ones were built by Ansaldo under license to a design provided by Armstrong during World War I or to a modified design for anti-aircraft mountings. After World War I, these guns were used afloat mainly on older warships and auxiliaries. About 730 guns were used for the anti-aircraft defense of Italy during World War II.                      

Cleaning Information
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.
