i know wikipedia isn't an rs but there is interesting probably or content about this over at essentially the flags were proposed and some plans were drawn up for them to be implemented i can't find a photo of togoland at the time that has any of these flags displayed indeed in contrast if they have a flag it is the german imperial flag see here i think i'd be wary about including the flags without an rs clearly establishing their credibility even if we put proposed flagthat seems problematic what are you thinking
