Good (tough) quiz. Just two comments: the country hint for the famous 9-57 is wrong. And I think I wrote the name of the bowler with a 20.97 average, but it wasn't recognised.
These pre-1900 bowlers would also have qualified if we'd included 19th century stats: George Lohmann (10.75!); Charlie Turner, Bobby Peel, and Johnny Briggs. The scary Fred Spofforth, with 94 wickets, would have just missed the cut.
