CUSIP numbers

Hello, This may seem a little trivial to some of you, but I'm just trying to satisfy some personal curiosity. I'm looking to ascertain the CUSIP number of a Bank of America credit card that was issued on 10/20/2001. I went to sec.gov and looked up the trust, which is BA Master credit card trust II / CIK#0000936988. That brought me here:

http://sec.gov/cgi-bin/browse-edgar?action=getcom…

The only document I found that had a CUSIP number at all was the 8-k filings listed on 2001-11-14. It's the one that reads "Current report, items 5 and 7." Here's the link:

http://sec.gov/Archives/edgar/data/936988/0000936…

Now, when I click on those files (ex: mt22094c.txt), at the top of those those documents it shows both a Class A CUSIP and a Class B CUSIP, like this:

CLASS A CUSIP 55262T AE3

CLASS B CUSIP 55262T AF0

Not to mention, if you open each one of those listed .txt documents that follow mt22041c.txt, each document will list CUSIP numbers where the 55262T is the same, but the last 3 digits are different.

So not only do I have CLASS A and CLASS B CUSIP numbers, I also have series of similar CUSIP numbers throughout the list. Is there a way to figure out in which bundle my account is?

Thank you very much in advance,

D.
