|The usual Combrig practices are used in the casting of the smaller resin parts, a casting sheet for platforms, large parts cast singly on casting blocks and resin runners for the bulk of the parts. The Colossus only has one, rather small sheet. This
sheet has the bridge deck, navigation deck, chart house, fore top control, conning tower catwalk, aft searchlight platform and aft navigation platform. The chart house has detailed doors and the fore top has incised vision openings. There are five
superstructure parts that are cast as singly. These are the forward superstructure, aft superstructure, amidships superstructure and both stacks. The forward superstructure casting has three levels. On the first level are four 4-Inch secondary
positions. Each of these positions has detailed gun opening shutters and a locater hole for the gun barrel. On the 01 level deck, there are locater holes for the tripod legs, locater holes for open 4-Inch guns, a well for the forward stack and two
lockers. The 02 level is the base of the conning tower and has port holes and doors. The top of the superstructure, level 3, is actually about 1 ½ levels, with the top of the conning tower and a sloping apron to its front. The aft superstructure casting
is the largest of the singly cast parts. About 40% of the size goes to X turret barbette. Forward of the barbette are two levels of the superstructure. The 01 level has corner 4-Inch gun positions with detailed shutters and locater holes for the barrels.
This level also features detailed doors and port holes. The 02 level has two more 4-Inch gun positions with shutters and barrel locater holes. Both the 01 and 02 level decks have numerous lockers. The 02 deck also has locater holes for the aft
conning tower, open 4-Inch gun positions, and support posts for the searchlight platform. The small amidships superstructure is two levels in height with port holes, detailed access door and ventilator locate wells at 01 level. The top deck contains
the well for the aft stack, deck access fittings with hinge detail, inclined ladder openings and a couple of small deck houses. The stack castings are significantly different in size and design from each other. The forward stack is far larger, being
longer, wider and taller than the aft funnel. A fine horseshoe apron is at the base and another apron at the top. The bottom apron of the aft stack is a rhomboid shape with a small ventilator at one corner and a fine top apron. The five main gun
turrets are identical and feature excellent crown detail. This detail includes a centerline crest, over-lapping armor plates and vision cupolas on the forward crown. The turret sides feature sharp lines at the angles and deep horseshoe shape gun
openings enclosing locater holes for the gun barrels.
There are 25 runners of parts with five of the runners having only one part attached to them. Three of the runners have gun barrels. These are the main gun barrels with hollow muzzles, the open 4-Inch guns with separate gun barrels and mounts,
and the 4-Inch gun barrels fitted in the locater holes in the superstructure parts. The last runner also has the parts for 3-Inch guns, navigation equipment for the bridge and aft navigation platform. Three runners have anchor gear, with runners for
three detailed anchors, and the other two with deck windlasses, Four runners have the numerous ventilators with runners for large and medium mushroom ventilators as well as small straight ventilators found around the edges of the barbettes;
another runner with two types of small mushroom ventilators; one runner of net boom brackets; and a runner with rectangular ventilators and two dinghies. Deck equipment fittings are found on three runners, One has only twin 24-inch searchlights
with separate pillars and searchlights, one has small cable reels, and the third has larger cable reels, along with aft conning tower, deck winches, stack base ventilators and small deck houses. One runner has only the detailed boat boom attached.
Two runners have boat davits. The last nine runners have only ship’s boats. Three of these are steam launches with each launch cast separately. Two are large and the other is medium in size. Detail is excellent on all three with cabin bulkhead
windows, crown ventilators, open cockpit, forward navigation position and a locater hole for the launch stack with open top. The open boats are in five different patterns, one large whaler four medium size boats with transom stern, one smaller
boat with transom stern and oars, and four pointed end boats in two slightly different sizes. The open boats feature bottom planking and thwart detail.
