If it makes a difference, it's not Sealskin. I contacted the seller who had indicated the craft was made in 1998 (and showed the serial # confirming it). I asked him when the skin was replaced since Sealskin wasn't out until 2000. He said 'oops', the skin had never been replaced but the person he bought it from had told him it was Sealskin and that he woud change the ad to reflect no Sealskin.
It's off ebay, but still on Craigslist in South Carolina:
