Congrats SPB, cool find!
Back in the 1920s young women (Flappers) carried small bags like this often attached somehow to themselves
with a belt sash or wrist strap. See the funny, chain mail, looking material of the pouch part of the purse? That's
a dead giveaway for the 20s. The place may have been a "speak easy or" a "house of blue lights". listen to "Mitch Ryder
And The Detroit Wheels" sixties hit "Devil with A Blue Dress On" you'll get the picture.
Looks like plated brass with a snap lid with a glass or porcelain snap down lid.
Best wishes!
