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
