Hi Flying Spud, I'm new to this site and saw your posting re Guinness, from your CIE Logo and Interest in Guinness would I be right in surmising you are either based in, or are an Irish Collector of Old Stuff ? If so we might be able to swap etc, this site is very good, but is primarily UK based, and that's fine, but it means limitations for checking items etc.....
Cheers -
Gerry
