For a look at the opposition why not try this page and check out the 1/72 Revell model references:

If you look at the rest of the site there are some really nice colour scheme examples for corvettes throughout the war and some other stuff.
This link has a work in progress report on one of these models using one of the aftermarket products (a skylight with 120 parts in 1/72 scale?)

Funnily enough it is very hard to find Royal Navy seamen for these kits (I found three sets compared with umpteen for UBoat crew) - the figures that come with the kit are about as useful as many of the other parts. So you need to be very imaginative to produce a harbour scene.
But they certainly brought out the boy in me again (never far below the surface) - I remember pressing my nose up against the window of my local model shop when I was a kid looking at a made up example.
