You Know The Voice: Henry Corden (1961)

 Character actor Henry Corden didn't move into cartoon work, I think, until after he'd appeared in this 1961 episode of The Lawless Years. 

Henry's toon credits include The Flintstones, The Hillbilly Bears, Thundarr The Barbarian, and a collection of guest roles. I think he used the voice from this episode, "The Victor Gorido Story", in one of those cartoon gigs.
