LOL - I have never known myself. Just about every font that was given such a number is a rip-off of a well-known font.
I don't know if you are familiar with: http://desktoppub.about.com/cs/findafont/a/fontaliases_f.htm -- it is a handy reference and lets you know all the "real" names for Bitstream fonts. I've started you off in the "F" section....
