The pull device at the end resembles another I have seen on a "how to spot a fake" website. I see your point about the color of the zipper, as well as the color of the thread. I saw one of the more recent posts also had a blue zipper with a brown leather.
What did you mean by a "pre-production" bag?
Thanks for your help!
A pre-production or Pilot Bag is a bag released in very limited numbers several months to a year or more before the full release of the bag is scheduled in order to gauge the buying public's reaction. I don't know what Coach did regarding pre-production bags that far back so it's impossible to say for sure if it might be one or if there would have been any kind of stamp or mark in the bag to show it was a pre-release bag.
As for the zipper, that "industrial-style" heavy-duty zipper was common in Coach's casual styles in the early to mid 1980s, but there are 2 problems with that kind of zipper appearing in your bag. One is that the Carriage Classics really weren't considered casual, they were more toward the dressy end of the scale and I can't see Coach using a casual type of zipper in that bag. The second and biggest problem is actually because of what you just mentioned about the zipper being YKK, since the zippers in that industrial style were, as far as I know, usually made by Talon, NOT YKK. Coach didn't start using YKK zippers until they started expanding production in the late 80s and early 90s, and I don't remember seeing that style of zipper with a YKK logo.
So that actually tilts the scale a bit more toward the bag being counterfeit.
And I hope that clarifies why those "authenticity guides" are so dangerous - not just because their information is usually totally wrong, but because authenticating a bag invovles SO much more than just looking at a zipper or seeing if the numbers in the serial are lined up straight! There are dozens of different things to analyze and if someone isn't familiar with that EXACT bag or family and also with Coach's designs and production methods during the time period the bag was supposedly made, they CAN'T make an educated authentication. There are no simple Rules and it requires an LOT of experience and actual research to be able to authenticate some of the trickier bags - and spot the fakes.
