I'm not sure what guides you are using. We recommend the Salearea guides: http://search.reviews.ebay.com/members/salearea_W0QQcpnameZmembersQQprZsaleareaQQuqtZg because there are a lot of guides out there with incorrect information. Because the creed of yours says "Made in the United States", that means it was made after 1988. Because the format of the number is xxxx-xxx, rather than xxx-xxxx, i.e. 4 digits before the dash, that indicates it was made between 1990 - 1993. Since the style was produced in 1992 and only made for a short time, I'm confident that your bag was made close to that date.
Thank you, I did go to eBay and read the listing and explanation of numbers. I feel confident you are correct. I appreciate your excellent feedback.
