I think the windows are slightly out - we had row 4 and I am sure that was the 7th window. Otherwise, about right. The long oblong block between the forward lav and row 1 was the 'galley'. Serving 40 out of that was quite a feat. IIRC, the block on the other side forward of row 1 was the closet.

And yes, the Rocket was about 40" pitch.

I've got quite depressed thinking about it now.
