Approximate "cover" date of September-October 1951 is based on the back cover "Now On Sale" house ad in Tick Tock Tales #32 which indicates that the two comics are contemporary.
The horses of Meagher are extremely elegant. The inking makes them appear shiny with the few inklines, or heavy clean blacks on muscles.
Joe Certa, John Belfi and Fred Guardineer are credited with Durango Kid stories in Jerry Bails' Who's Who. This is Certa. Guardineer (Durango Kid #20) has very small eyes on his horses and faces, and gun holsters usually without any straps across, where Certa and Belfi (Best of the West #4) has one or two. Belfi often assisted Certa in inking, but if you notice the hairline under the hat of Durango, it is a broad V-shape, when Belfi in #4 has more waves. So this must be inked by Certa.
