Pre-Columbian vessel? [4284×5712]

I was at my parents house this weekend and was looking at a vessel that's been in my dad's family since around 1900.

This is the information that my father has about it.

Peter & Caroline Wiot – my dad's grandfather & grandmother.

The jug on this picture was given to me by my mother when she broke-up housekeeping and moved to Columbus with my sister in 1975. Her dad, Peter Wiot bought a half section of land around the turn of the century (1900) directly from a Native American and when the sale was completed, the Native American gave this jug to Peter. She never knew just what the jug was for but the Native American that gave it to Peter held it in high esteem. Mom talked about the Choctaw Indians so perhaps this came from one of them.

I am not sure just where the land was located but it was near Idabel, Oklahoma in McCurtain county.

The Museum of the Red River in Idabel, Oklahoma. The Museum's collections feature archaeological artifacts of the the Caddo and Choctaw, Precolumbian objects from Middle and South America, modern and contemporary native arts and crafts from throughout the Americas. The Museum also displays representative works from African, East Asian, and Pacific Island native cultures.

I've scoured the web and people have said it's a stirrup-spout vessel. After researching pre-Colombian stirrup-spout vessels, I can't find anything that looks like this. My father did say the handle is hollow. Any ideas or info would be greatly appreciated.
