I did some Googling. Are you talking about the saffiano leather one that was made for factory? According to the
eBay listings I found, the retail was listed as $398. I am assuming that was the price printed on the tag. Of course, factory items are typically marked down from that price.
Coach also made coated signature canvas train case as well. I also found some info from 2008 about Penelope Op-Art train cases and suit cases, but those were made for FP.
