I don't have a print or scan but have seen photos of the mono screen overlaid over the top of a KVA based screen.
If you going to make a steel windscreen frame, I would suggest you get yourself a screen to start with a build from there.
I have seen photos of fiberglass roof sections that have been cut and shut to better fit the windscreen as well.
So work out what screens you can get locally, and go from there. Here in Oz, it would be a few thousand to land a Pilkington manufactured original shape screen from the UK (at a guess). Whilst a KVA screen is only a few hundred.
