Walden Kayaks Model Timeline (or more info)?

Recently purchased a Walden Voyageur for my wife, and got to wondering about its history, etc.
I couldn’t find much about this particular model in searches.
From what I’ve read, the Walden factory was about five miles away from me in Ayer, MA, before they went out of business, but also maybe in Concord, MA prior to that?
Is there a timeline of models and dates or maybe discussion groups that I can’t seem to find?
Thanks for any help or suggestions.

All I could find was this article discussing the business closure.

Many years ago I owned a Walden kayak. Can’t remember the model name. Very short. I remember that it was very stern heavy with me in it, otherwise it was a good little boat. Ended up selling it to a guy at work.
