Morning Wez. I had one of the 47" but found it a bit big for moving around so sold it and I'm building one at 1:12 now.
That cockpit has definitely got to go and the two oversize and wrongly positioned hatches! 😮
I've yet to tackle the windscreens for any of my builds but I know some folks make a former and gently heat the plastic round it.
The drawings that Cornwall Model Boats sells plans for is the simplified 1:16 version though probably fine for the cockpit and hatches. Anyway, I'll have a look through my Fairey drawings and see what I've got.
Online photos are really good for sorting out the details though.
