Yep, the PR.XVI had the bulged side windows, replacing the earlier "blister" type as used on the PR.IX and earlier Marks. as the PR.XVI had a presurised cockpit and, as with all other models, the only opening windows were the "quarter lights", which hinged inwards for clear vision, if needed, on landing.
The "blister" on top of the canopy was sometimes fitted to late PR.XVI's, but it normally ahd the "flat" escape panel in the roof, the blister eing standard on the PR.35.
