Thank you for all of you/for your answers! There isn't anything pressed on the leather (lid) (Old-N-Feeble, summicron1), and yes the focusing panel was with this camera (Old-N-Feeble).

I found something interesting/similar (to my camera) on Camerapedia: First_plate_folders,"The First or First Camera Japanese 6.5×9cm plate folders, distributed by Minagawa in the late 1920s and early 1930s, and ostensibly made by "First Camera Works", another name for Kuribayashi". What do you think?!
