The Mark IIA was a modification of the army's Mark II anti-tank gun fitted with Molins auto-loading gear. Used by many MTBs in power operated mountings to give them a bigger "punch" when attacking barges and small vessels. It was also proposed to use the Mark II without the auto-loading gear as a wet mount for submarines but this never made it out of the prototype stage.
The Molins auto-loading gear carried seven rounds, one in the breech and six in the feed system. An additional twelve rounds were carried in ready racks on the naval mounting. The last round could not be fired, a precautionary measure to prevent the feed from running out of ammunition which would have necessitated manually working the breech mechanism.
Unlike the RAF version, this weapon allowed only semi-automatic firing.
These guns were of monobloc construction and actual bore length was 42.87 calibers. About 600 guns were produced with Molins gear.
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.
