This reminds me of an old doctors bag
1960s top handle strap black leather purse
Clasp closure at top
Long enough straps to wear over shoulder but think it’s meant to be worn at the wrist
Lined inside that’s pretty beat up on the bottom
Some normal wear and tear on sides of bag
Check last photo

Zippered pocket inside
Outside on front and back there is a pocket

Measurements taken are
