Thinking about these two quizzes, it crossed my mind that the "hundred hundreds" is likely to be quite hard to achieve in the future, the way modern cricket has gone. The best players nowadays actually play quite a lot less first class cricket: the test squads don't play a lot of county stuff, and the Australian system seems to gravitate against old men playing first class cricket. It's remarkable how many of the players on the lists had careers over 30 years long. IIRC, Fred Titmus's career spanned 5 decades. His first class debut was in 1949 and his last match was in the 1980s.
After I typed that I checked on Wiki. The first sentence about him says:
Frederick John Titmus (born Somers Town, London 24 November 1932) is a former English cricketer whose first-class career spanned five decades.
