Something I'm enjoying about seeing these noids of varying ages, is that I start seeing patterns that are clues to the time they were introduced. Rob, #s 2, 10,12, and 16 look like the oldest varieties to me, like pre 1900, 11 and 14 make me think 40s or 50s. 3-9 make me think 60s and 70s, and #2 looks after 1980. That's all a guessing game of course, but it is cool to note traits that started becoming prominent at various points in time.
