OK, I42, bearing in mind hey are left and right views;
here is a flickr link which, when you get past the ads has images of a Westland Whirlwind as photos and the drawing I reversed the colours on. This
link is a page from AP 1709 Vol 1 which as everybody(?!) knows is the Westland Whirlwind maintenance manual.
Hope that clears things up for you, I know how frustrating these can be.
OTOH I see what you mean, the access cut out on the stbd side?
