I'm wondering if the AII were sold only in Canada, or if it were sold here for a short time; because I've never seen one on eBay, Craigslist, or other online shopping sites.
If I remember correctly, the model of the AII was 1676--the same as the first AIII's model, so they're essentially the same cleaner.
Here are the models and colors of all the AIIIs(there was only one Ambassador and one Ambassador II):
C101A - navy & light sand
C101G - gray & coal
C101H - oyster & fog
C101J - white & capri
I hope you can find an AII that's in good shape.
