The diagram shows that this was originally a Union Pacific locomotive, but Locobase cannot match it up with any owned by the UP at the time. It also explains that the AV & W was opened between Tulsa and Enid, Oklahoma in 1903 and that that line extended to Avard by 1904. In only 5 years, the AV & W was sold to the Frisco and redesignated as the Perry & Avard Sub-Divisions of the Western Division.
So clearly AV & W #8 was a second-hand engine. But more cannot be determined.
