Regardless, archives do not show Scout in UN livery, armed with this information, we'll search again. That said, we are all volunteers and if we get it wrong, it is sometimes because we are looking in the wrong place or others have information and they haven't offered it or we haven't asked the right person. Record keeping from that time isn't an Excel spreadsheet with a Ctrl+F function.
Being proved wrong sometimes throws up more questions than it solves!
