Fascinating - thanks for sharing this info, Hyacinth! You estimated that the Stewardess I got was probably from the mid-1980s, so that would make sense in terms of dates.
I was curious because I've only found a few references to Coach bags with Falcon zippers (one from eBay: http://www.ebay.com/gds/coach-buying-guide-for-newbies/10000000009867660/g.html; and one from a Goodwill store: http://ourgoodwillstore.wordpress.com/2011/07/07/how-to-authenticate-coach-bags/). I wasn't sure how reliable either is, so I wanted to run it by the experts here!
Thanks again.
There are at least 7 or 8 brands that they've used, maybe more. It's a pretty safe bet that if the bag is genuine, so is the zipper. And with very rare exceptions like the fakes with "Coach" stamped into the zipper pulls, zippers should never be used for authentication.
