Here's a Clarrie Grimmet field setting from http://www.pitchvision.com/
care of Richard Welch, he said -
Here’s a jpg of Clarries field – I found this in an out of print coaching book from the 40’s or something, I forget exactly where, but it does have good provenance!.. and also a Bill O’Reilly field as documented in Don Bradman’s “the art of Cricket” (1948 edition). Bradman says that this is the field O’Reilly usually bowled to – which is incredibly aggressive (“Aggression rating” of 85.6 to Grimmets 59.7 which is a massive difference.)
