Rootie, it looks like Watson was running both a coilover front suspension as well as a 4-bar setup at various times during the 1961 season on the Leader Card dirt car. And that right front spring almost looks coil bound in your photo. He also used the coilover setup on his roadsters in 1961 for both Ward and Johnny Boyd with less than spectacular results although Ward did manage to get a win at Milwaukee. The non adjustable shocks of the day likely weren't up to the task. At any rate Watson was back to torsion bars in 1962 although his later dirt cars did use coilovers again.
