Sometime just before Bradman appeared, the rules of cricket became a lot more universal, but previous to around 1920 most umpires/players would have taken the rules from any number of commercially printed books that were sold as rulebooks, which contained contradictory provisions, along with umpires interpretating other rules differently.
The most fiercely debated rule was the boundary rule. I believe (I could be remembering this wrongly) in the original attempt to codify the laws in 1744 by the MCC, they used the verb "strike" in the rules that had a slightly different contemporary meaning. The rule, as was written, was to score a boundary four the ball had to "strike the boundary rope", and only then was it considered 4 and dead ball. Many umpires took this in a modern literal sense - if a ball went over the boundary but did not strike the boundary rope, it was considered live. Many umpires considered that impractical, and gave 4 runs.
You would have situations therefore in some matches where a batsman would smash one into the crowd, and they would continue running until the ball reappeared. The reason sixes were counted out the ground was a sporting way in these situations of only running 6 if the ball ended up 100ms outside the stadium in a pond. So while he might not of had any sixes, he might have hit one into the crowd and run 5 or 6.
After 1920, the MCC re-published its own lawbook which was seen as definitive.
