Padgett,
Here's a pic from Chris Chance's Bio on the Fat Chance website, you may have a very serious grail bike as it's just like this one.
You should reach out to him with the s/n and see what he says.
Yours has the same parts that are left on it, looks like the fork is original.
This will be important to leave original despite being rough it should clean up well.
This just turned into one h**l of a find.
