Who is the first cricketer to hit 6 six's in an over in domestic?

Ravi Shastri was the first Indian cricketer to hit six sixes in an over in domestic cricket, achieving this feat for Bombay in a Ranji Trophy match against Baroda in 1984-85. He hit Tilak Raj for six consecutive sixes, becoming only the second player in first-class cricket history to accomplish this at that time. Kapil Dev and Sachin Tendulkar never achieved this in domestic cricket, while Srikanth and Amarnath did not have this record.
