I’ve had these boots on display in my home for years because they are too big for me to wear and the patina is rich and warm. I love looking at them!

They are brown cowhide with genuine ostrich vamps. They were sold by Tener’s Western Outfitters (Est 1930) of Oklahoma CIty. Tag inside. Embroidery on the shafts are 10 rows o tight stitching wide. Very high quality. Leather soles. Heels might have been redone. Left boot has a tear in the leather at the back upper heel, does not go all the way through,. Looks closely at the discoloration / patina of the shafts in the close-up photos. 

Stamped 4750 3193 3210 inside.

No size. They fit me like a ladies’ size 8.  The soles measure 10 3/8” long heel edge to toe stitching. At the ball of the foot they are 3 5/8” wide stitching to stitching. You might want to measure your own boots to see if the size matches. 

Shaft is 14” in circumference measured on the outside. 

The leather could be conditioned. It is not stiff and they are totally wearable. Some dry spots in the back. The insole is comfortable. Front he smell of the leather I would date them  C. 1970s to 1980s.
