366th Brass Insignia

[Ray Scott]

I need help identifying a small brass screwback pin I found in an old fort burn pit. I think the pin dates to the 20's or 30's. It says 366 at the top, has two pine trees at the right and left, a crossed axe and pick with a rattlesnake in the center. It had a banner at the bottom but it's too corroded to tell if there was any writing.

I know the 366th Infantry regiment was a segregated unit that saw action in both world wars but this pin does not match the 366th unit symbol.

If anyone recognizes it or knows of someone who would, please let me know.

Thanks
