I had previously identified this photo as Jim Lange, but it is not! Jim Lange originated the role of Captain 11 on WMIN in late 1953. He played Captain 11 until November 1954. Eventually Chris Wedes took over as Captain 11. But between Jim Lange and Chris Wedes, another actor played Captain 11. At this point, I don’t know who it was.
Here is a picture of Jim Lange as Captain 11
And this is Chris Wedes as Captain 11
