There are post-prototype, pre-production Lisas and Apple IIs as well. They often came with a really nifty custom made traveling case so a salesman could take it with them and set it up. They're fairly rare and pretty cool, especially if you have the travel case and sales literature.

Since this was Apple's first portable, it wouldn't surprise me if this demo piece was intended to go along with a salesman to show off to various companies. It'd be worth looking inside, I've heard about Apple putting in upgrades and other things to make them faster than the production model.
