Thanks for that James,
Of course, I'd forgotten and only noticed when I went down to the shed earlier, that the Stars & Stripes was hung from a gaff, lifting it above the rest of the hoists on the yard. This still leaves the question of whether there is a particular structure to the rest. I use HNSA and Navsource a lot and HNSA has a whole screed on when to fly particular 'honors' etc. along with gun salutes, foreign dignitaries etc., religious services etc. but I've decided to follow what simple evidence I have from photos where, when single flags only are showing, they seem to start at the outermost starboard point. Whether this is the rule or not..............

PS You're building a beautifully crisp model of HMS Onslow. How much patience you must have on the 'fiddly' bits.
