Charles H. Dillon (1889-1967) worked in different capacities for Western Union in Dallas, Texas. In the 1940s and 1950s, he wrote articles about the telegraph for the Texas Almanac and other publications. He also wrote newspaper articles. In 1958, his book, A story of the telegraph and the Western Union and how they reached the southwest was published.
I'm seeking help finding the publication specifics for a lengthy newspaper article Charles Dillon wrote titled, "Inventor's Offer of Perpetual Patent Rights to Telegraph Ignored by Texas Republic."
I'd like to learn the name and date of the publication (hopefully with page/column number references).
Digital images of the lengthy article are online by Frank W. Shiels (Fort Worth), Crown Jewels of the Wire, April 1983 Archives (Letters to the Editor).
A graphic of the opening part of the article follows.

Update 1: This date I spoke with two officials at the Dallas Public Library. While we were not successful in finding the article, I did learn one long standing Dallas paper is no longer published, the Dallas Times Herald. Although issues of this paper are held on microfilm by the Dallas library, no extensive digitization or indexing of its issues has been done. Discussion lamenting all of this online in a 2010 thread, Phorum, "Dallas Times Herald Archives." (I did find that NewspaperArchives has a very few (about 10) early editions of the Dallas Times Herald in its collection, but nothing that would help me.
Update 2: I heard from Casey Greene, Galveston and Texas History Center, Rosenberg Library (Galveston), over the weekend. As a clipping without further reference, the article appears in their vertical file "Telegraph." It was carefully clipped and then glued to cardboard backing--leaving almost no way of developing further clues about where or when the article might have been published. Although not publication specifics, I now have the next best thing--a solid reference to the vertical file at an established archive. It works for me.
