The Blue OA sashes were actually given to overseas arrowmen in either the 70's or 80's and were very rare back then it was given to prestigious arrowmen in overseas lodges and yes they were not authorized by BSA or the OA but you have to put into thought that the OA was not an official BSA program for many years and further more the black oa sashes we the original ones but they did not have arrows on them the had a white stripe on a black sash. they were around for about the first 3 or 4 years of the OA.
