Vintage Large Medical Doctor Bag Leather Brass British Lever

Description

Vintage Large Medical Doctor Bag Leather Brass British Lever.
Beautiful bag. I just barely locked it and can’t get it open to show the inside. I can’t remember how and I don’t want to break it!
Approx 22” wide and 16” tall with the handles.
If someone can tell me how to open it I can send pics of the interior. 😊
