The linen parts of the aircraft were varnished, as was usual at that time.
The wooden pieces leading to the hood were also painted white.
The metal hood and spinner were treated against corrosion by a coating. Judging by photographs, this was not a clear coat, but possibly treated with a coloured varnish.
The colour is fact very similar to the rest of the unit and is clearly not white (painted metal).
