Deluxe, I did some digging and here's the scoop: They were made one year only, 2002. There was quite a run of them so they were around for years and years but they didn't sell well enough to continue production. They are USA made which Is cool. The mud puppy color Is a fantastic looking color!
Now, some of the packaging might say '98 but It was fairly common at the time to use whatever was on hand package wise, If that makes sense.
