Be cautious of restored aircraft. The wartime spec for the wheel bays was a zinc chromate rear wall, which is the main spar, with the rest in clear laquered aluminium, including the gear leg and main doors. Although most period photos show this, and the info comes from the finishing specifications, it's possible that some might have been painted during deep servicing.
The gear legs were coated in a finish which included powdered aluminium, giving them a silver-grey look, with the axle yoke in dull, grey metal.
