Who was the only Indian Test Wicketkeeper to have opened India's bowling attack in a test?

Budhi Kunderan (spelled Kundaran here) was indeed an Indian wicketkeeper who opened the bowling in Test matches. This was unusual as wicketkeepers typically bowl later in the innings, but Kunderan was a capable bowler who could open. Kirmani, Dhoni were pure wicketkeepers who rarely bowled, while Gundapa is a distractor name.
