There was a big discussion on this board a while back about whether or not the classic arrowhead shirt insignia was Enterprise specific or fleet wide. The shows broadcast gave the impression that each vessel or posting had a unique one with the departmental symbol being common. I believe it was settled by a copy of an interoffice memo which made it clear that the arrowhead was supposed to be universal but due to production errors was not- the memo was intended to correct that. That discussion has either been rolled off the archive or was a secondary one inside a different topic. Could anybody point me to the way to finding the original thread or post a copy of that memo here?
