for anyone that knows the marque I am looking for a curved screen not the angular sort. I believe they were also fitted to Christina's. Starboard front glass or whole screen required.

I hear on the grapevine you've got the boat in Dippy Danny's yard?
Have you asked Scarron about a screen?

I suspect making a replacement will be your only option, in which case, you'll be looking at acrylic or polycarbonate plastics, talk to Precision Units in Poole, if you make a buck, they have an oven to mold a sheet over it. They are the first port of call for the Fairey Fraternity.

Having got large quotes for a replacement perspex unit and in view of other expenditure required on the Triana I decided to save cash and have a go at making and fitting my own. I constructed an MDF mould matching the curves and shape of the inside of my screen. Then watched lots of videos of guys bending perspex. my new front half screen had to have a virtually right angle bend in it.
The original alloy frame was not brilliant but needed to be reused, it was bolted together and needed quite a big clean up to get it ready for the new screen. needless to say the screws were well corroded and some needed careful drilling to remove them. inside the screen extrusions were steel threaded joining plates some of which had to be remade. Then on with the screen bending
I made a a brown paper pattern of the well misted but intact original screen and cut out a new blue tinted perspex blank on my bandsaw. Next I made a shallow ply wood lidded box that would contain the blank and the heat I needed to allow the bending. I took the perspex off cuts and used these to perfect a heating technique using a big halogen lamp and two heat guns. The offcuts needed 100 + C and about a 30 minute heat soak to become pliable. Then inserting the blank and donning welding gauntlets, the heating process began.
After 30 minutes it was now or never, I removed the blank and draped it over the mould being careful to line it up with the outline of the original drawn on the mould. After cooling I tried it in the frame and with a bit of judicious trimming and persuading it fitted........... I created screen seals from sheet rubber and proceeded to bolt the screen frame together, over the windscreen section then mastic sealed the inside and outside edges - all rather Heath Robinson but ........result!!!
