Know the Answer?

This is for the boxing detectives out there. Perhaps someone knows who the boxer in the story was.
The story titled "Nat Siegford Does it Again: A Christmas Story," caught my eye as I was processing The Ringside Reporter magazine. The issue is dated January 8, 1950, Vol. XXII No. 1. I read the whole story, and loved it. It must be true, seeing how Fred Eisenstadt was a writer of good repute for Ringside.
It may also be untrue, but whatever the case, Eisenstadt is writing about a man whose life was drastically different compared to the times when he was a boxer.
So, here is a question, which I too would like to know: Who IS the boxer in the story? There are clues that a good boxing historian may follow.
The boxer fought against "top-ranking welterweights of that era." That era being the 1920s. He fought against "Phil Bloom, Kid Graves, Jack Britton, Ted Kid Lewis, Dave Shade, Mike O'Dowd, Steve Latzo, Sailor Freedman, Harry Greb, Ace Hudkins, Soldier Bartfield, Honey Mollody, Pete Latzo and others--in a career which lasted some eighteen years."
