I can't help you directly, but there are a couple services I'd suggest:
First:
WhatTheFont? , if you have an image of the logo you can upload it here and it will try and guess an equivalent font, it's not perfect, but I've had some luck before.
Second:
Identifont , this one you answer a serious of questions about the font in question until the site wittles the list down to a few options that should match pretty close. Now, I've this service before and it didn't get exactly the right font it definetely got me close, but this isn't the same site I used(looked through my bookmarks, can't find my old one), so I can't really say if this is as good.
