Haha. Using the list Mike listed I found the mail car, and I can get a replacement mailbag... in fact ebay has them in a group of 10 (cause they will be lost within 5 minutes, I presume

They don't have the metal pin required to attach to the magnet on the mailman though. I almost want to buy some replacements even though my O scale stuff is boxed up in the attic... Yeah, I'm anal like that.
