The corvettes had wood deck sections forward, around the forward gun mount. Everything else was steel. They would have used wooden duckboards on the bridge decks. If you're painting her up in Western Approaches camouflage, the steel decks were painted MS2. You'll find that and all other wartime RN camouflage colors accurately matched and available in our Colourcoats enamels. No minimum order on paints, and we ship worldwide.
