Flask bottle

I’m not real familiar with bottles, but I believe this might be a turn of the century flask type, half pint.
If anyone would like to help identify it, it would be appreciated.
“ONE HALF PINT” with “91” or (16) embossed on the bottom; that’s all I have besides the pictures.
Note: oddly enough, after rinsing the dirt from it, I did realize there’s a electrical connector inside 😅

The seam goes all the way up so it was made in a mold. No refill warning so before 1934.
