I doubt very much if they even saved many, if any, examples of previous styles, the only records they had were probably some production records or notes on paper, and maybe their catalog files. And isn't the Archive located in the old original factory building? There probably wasn't any room for an archive back when the NYC production facilities were still active. Later in the 1990s between moving production to China, repurposing the old plant as the corporate offices, and putting only what they considered "important" records on their computer system, there's probably a good-sized chunk of
Coach history that's been lost.
I've seen it mentioned often on Antiques Roadshow. When a company makes changes in purpose or ownership or just moves their offices or plant to a new location, a lot of old paperwork and production samples including important company history are simply tossed in the dumpster or on the bonfire. It wouldn't surprise me if Coach did something similar. Saving their history is something that many companies (AND cities, Chicago being a perfect example!) have only started to consider doing in the last decade or two.
I'm sure the "missing" Dakota style would have been style number 4202 since that's the only number I can't account for. There's a debate on what name we should call it though. (Hey, we tPF'ers named the Baby Sage so why shouldn't we be allowed to name a nameless Dakota that we "discovered"?) My personal choice would be Sundance, since we already have a Dakota Cassidy and I think the Sundance Kid deserves equal time, even if my heart will always belong to Paul Newman. But Robert Redford made such a GORGEOUS Sundance Kid.
