JVJ has "Fred Bell ?", and Bell can be found in issues #31 and #32 to compare with. Horses and inking are not far off. He is credited on Charlton comics, but not on westerns.
Inside front cover.
Allison is credited to Charlton's Jesse James (unconfirmed) by Jerry Bails' Who's Who, but he is credited to over 20 stories in Cowboy Western, and comparing the art, this must be him too. JVJ also has him as artist.
JVJ has "Thompson ?" on this, but not very much like his two signed stories in New Heroic Comics #90. Another suggestion by JVJ is "more like Lee Ames", but he has hands with "interupted" lines between the fingers (Avon's "King Solomon's Mines"), and that is not present here. Inking here also has more black shadings.
Art identification by Gary L. Watson and Jim Vandeboncoeur (12/2008). While "Jessie" is used in the feature name, "Jesse" is used throughout the story.
JVJ has Homer Fleming, and it compares very well with a signed page from DC's "Buck Marshall, Range Detective" and one from Gilberton's "Tom Brown's School Days". He is not credited to Charlton Jerry Bails' Who's Who.
This story is drawn by three Italian artists using the pen name EsseGesse, taken from the first letter in their names as pronounced in Italian.
