OK, that's wierd.
The first time I clicked the link it went here
http://www.ebay.com/itm/Antique-Buff...21168749038%26
Which is a Buffalo brand pouch/pack from a different seller.
The second time it went to the Polar Bear pack.
Maybe, but they conveniently don't show the cancel on the tax stamp. It's at least the right series, but that series was used for a few years.
