6-b-VI is a tentative assignment due to the lack of a killer.  It could possibly be a 6-a or something else; however, I have 74 examples of 6-a in my collection with the lastest date 1 Feb 04 and I believe 6-a ceased to be used around that time.  I would be very much interested to hear from anyone who has an example of a later use of 6-a.
