Looks like a pretty standard Lisa 2/10 to me, so no "L@@K PROTOTYPE STEVE JOBS" with this one. Not a converted Lisa 1 either.
More pictures will be helpful to see whether you've got something that was cobbled together from parts or sold as a single unit. What does the back look like? What's behind the front and back covers?
What will be special about it is how much of it works. Is there a Widget hard drive inside, and does it function? (That would actually be pretty special!) How about the keyboard?
