yeah, the screen is scratch, all out of styrene. The hinge is made from short, thick sections of plastic tube fixed to the canopy, with longer bits of brass tube attached to the screen. The difficult bit is getting the pin in!
The problem with it though is that on the real boat, to hold them up and together there are locating brackets, with a wingnut-ish thing to hold them together. I don't think I could make a working set at this scale, so mine are imitation. They hold the two side screens up well, but the front panel has a tendency to fall forward.
