Pretty much. The strips are mahogany bought from the local model shop, they were pinned to a jig I'd made using the plans as a reference for the curvature, after being soaked. After they'd dried, I offered them up to the model, cut them to size and superglued them to the frames.
I actually cheated a bit with the side benches... The air cases are in fact a single length of balsa, carved to fit the model, with various notches cut in it to give the impression of separate boxes. This was to avoid having to make lots of individually shaped boxes that you can't see under the benches anyway. (In fact on a Liverpool there are two rows of air cases under each bench) The frames for the bench are fixed to this block because when I made the jig up, the planks didn't curve enough, so there was still tension in them when they were bent into shape on the model. The first bench I made was built up off the model, and only fixed down near the end of the build. The finish on them is half-a-dozen coats of varnish.
