Perhaps this wasn't an issue in the past,or atleast not one that is monitored as closely as it is now,but did you ever see footage of a bowler that you were too young to see live,and wonder if the action was completely legal?
I was going through some footage of Trueman today,and i thought there was a very prominent chuck on some deliveries.

Watch the clip from 0:40 seconds on.
Any other bowlers from the past who have made you wonder?
