If someone in the Fresno area could look up his name in the Polk City Directory (Fresno)1945 & 1946. It sometimes will list a business name after the person's name. It could have a club name. If the business opened up in 1945 it might not be published until 1946. The Directory would be at the public library. And sometimes available online.
Gene...I would look into it for you, but Fresno is 3.5+ hours from me.
