I'm a little late to the discussion but I think you're unduly restricting the kind of help you're asking for. You claim to have a single photo of an aircraft that is not the subject of your book. I don't think you'll find providing that bit of info will handicap the subject. A lot can be found just by collecting bits of info. I've constructed the appearance of many aircraft by gathering a photo of a tail here, a bit of nose art there, some educated guessing from someplace else. I wish you luck in your search but it will be unlikely to succeed with just a sliver of info.
