Wow. You learn something new everyday. I heard of the Superba, Imperial and Custom, but never the Patrician.
Is the 19 model series the one with the shorter upper wash arm that did not do well in the corners of the rack?
What would be cool is if one of you KA experts could make a list of the series with some of the major highlights or features introduced in that series. For example, reversing motor drain, first model with an upper wash arm, upper wash arm increased in length, etc.
