Early 20th century metal case
The box has a nice handle to carry it and still has its original key. This tape is from a law firm where it was probably used to cash out clients.
The interior is painted red.
Note, the opening is a little capricious but works. You have to lift the flap when the key is turned halfway, otherwise it turns in a vacuum.
Dimensions: height of 10 cm, length of 25.5 cm and width of 18 cm.
