|From GT Nobles, the insignia is red on black|
Looking at this, I see a fictional group called the Order of the Arrow that honors scouts, and rarely has the Imperial family as members. Could Loren Wiseman, Jon F. Zeigler, or those listed as "Additional material" have been Scouts or Scouters? If so, it's a pretty nice inside joke. As it's not listed in the Traveller Wiki, I don't think anyone else has caught this.
Or perhaps I'm making a mountain out of a molehill.
