Windows
That's a good question Roger, I haven't got to that stage yet.
What I thought I would do was to cut the Perspex to fit into the window opening and fix with a touch of Canopy Glue.
It would have been nice if the window frames had been a touch smaller than the windows.
I hadn't thought of putting thin plastic between the frame and cabin sides.
Perhaps some of the more experienced fireboat builders will come to our assistance 😁
