Thanks!
To clarify the multiple name problem - the first photo shows the 1970's Crescent Bag, style 9235.
The second photo shows the Saddle Bag style 9988 which wasn't made until the late1990s and was an remake and update of the original Crescent Bag.
The third photo shows a 9134 Hippie Flap Bag from around 2000, the fourth a Hippie Zip 9146 and fifth a Utility Hippie 9404 from the same time period. There have been more than a dozen different bags that included "Hippie" in the name but never just a "Hippie" Bag and Coach didn't use the name in connection with the early Crescent Bag AFAIK. In general, "Hippie" most of the time just refers to a bag with straps attached parallel to the face of the bag that's usually flat or nearly so and that fits snugly against the body.
So if it's the first one you're interested in, using "Hippie and "Saddle" just ends up being confusing. Those names might be used by sellers either unsure of their bag's correct name, or by sellers throwing as many similar style names into their listings as possible to show up in more Searches, so using them in an Ebay Search may turn up one or two. But the three names at least when talking about actual Coach style names refer to three different kinds of bag.
