Ah yes Bill, I remember the AD & Horch. As I told my wife, Nancy, after she returned home this afternoon, "I don't mind losing to Bill, as I have gotten my share from him." As it turns out, I was "napping" through this one as well. I'm sure, at our age, you understand "napping", after all I have to be ready for the next Pro transfer at 4:00 am.
I am surprised that you only have only 6 entries on your "solved" list. I currently have 31 entries on my "ready" list, but I doubt that I will actually solve more than about 25% of these. Then we have Gerd out there, who probably keeps no "ready" list, but just snaps the correct answers "off the top of his head", as they arrive at the Pro level (not to mention PJ).
Have a good evening Bill, and "Happy Puzzling".
PS: I think I missed wishing you Happy Bithday!
