Not enough contrast plus from the files it looks like Prof Dakin, the RAN’s Technical Director of Camouflage, designed this scheme on Canberra. There is a note of his suggested colours which were “No.2” for the dark areas and “No.3” for the light areas. These numbers corresponded to the colours on a standard panel supplied by Garden Island (https://en.wikipedia.org/wiki/Garden_Island_(New_South_Wales)).
Dakin had been experimenting with specially mixed colours for the RAN since the summer of 1941 and one can speculate that No.2 and No.3 were similar to/a development of the two colours, a darkish grey and a blue grey, that he used on the port side of Perth in her final scheme, but green greys are also possible.
Given his comments/advice to the RAN on camouflage since 1941 it is inconceivable that he would not have specified painting the decks a dark colour.
HMAS Canberra completed her last wartime refit in May 1942 and she was apparently finished in a stark 507A, 507C and White camouflage scheme. Later she was repainted in Chicago Blue and was sunk in this scheme.
I wish to complete her in the 507A, 507C and White scheme, but have been unable to ascertain her deck finish. I tend to believe it was wood, rather than a dark grey paint colour, but have no definitive evidence to determine this. The area around/under her 4-inch guns is definitely wood as shown in a number of images of this area. Can anyone please confirm her deck colour finish
Further to this she was apparently fitted with at least six 20mm Oerlikens, but retained her single 4-inch HA mounts, but carried no pom-poms.
Is anyone able to provide the location, other than those 20mm on her turret tops, of these weapons.
