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: {http://www.suffolkregimentmuseum.co.uk/monthlyobjects/imperialgermanflag.html 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?
