The only information I could find about this meat company was within the text I found on a web page. For reference, I have copied and pasted the information below here.

The Stockyards District of Oklahoma City, now known as Stockyards City, is a special place in which to experience the history of the city. It is rich with the activities, yet it is also an alive and thriving business district today.

In May 1909, representatives of the Nelson Morris Company in Chicago met with early day Oklahoma City businessman and proposed building a packing house, if a $300,000 cash bonus and property concessions could be obtained. Led by Anton Classen and Charles Colcord, an Industrial District Company was formed. A tract of land west and across the river south from the downtown area was obtained and the company began selling lots to raise money, matching the gifts pledged by individuals. A second packing house followed suit and the beginnings of "Packingtown" became a reality. This began one of the most important building booms in Oklahoma City history.

The Oklahoma National Stockyards Company began operating as as public livestock market in October 1910. Morris & Co. (then Armour) opened a large meat packing plant adjoining the stockyards at the same time. The following year, Schwartzchild & Sulzberger (then Wilson) opened a similar plant. Together they represented an investment of approximately $3.5 million. The entire operation generated 2,400 new jobs in a city with a population of only 60,000. The stockyards and meat packing plants were Oklahoma City's first major industrial installations and represented the heaviest concentration of labor in the capitol city.

In the first five years of operation, the volume of livestock handling increased by 130%. By 1966, the Oklahoma National Stockyards had become the sixth largest market in the nation on the basis of livestock handled, representing $125 million in annual business. When the number of saleable cattle soared to 919,280 head in 1973, the stockyards took the nation's lead. Today the stockyards remains the world's largest stock and feeder cattle market.

From the beginning of this growing industry, a supporting community of goods and services was established. The streetcar was extended to this business district and it became known as "Packingtown." A post office was opened along with a bank, hotels, restaurants and a wide range of businesses related to the cattle trade.

Much of the original business district remains intact, maintaining the rugged western flavor but broadening their marketing approach to serve the needs of the larger community. Western wear attracts a wider scope of buyers today and the original home of western gear maintains stores in the place where western activities are still a way of life. The colorful, working world of the Stockyards provides a view of history unique to the present day activities.
