Worked a treat. I downloaded an older version of the PKZIP application note, and everything became clear. The mysterious two bytes at the beginning are the version number (I assume of the version of M$ CryptoAPI used to create the store). I very vaguely remember something about it now, but I am using a newer version of PKZIPs Appnote, which for some reason omits this info. Kicking myself now. Thank you for all your help.
