Another possibility...and maybe more likely yet!...a violin hanger for a music stand. Lots of fiddle players took up the reeds in the 20s-30s to make themselves more versatile.
The screw end would tighten onto the upright of your stand, the peghead would rest on the 2 curved flanges, and the bow might hang on the lower flange.
Here's a present day version.
