Hello Hauke Marxsen

The Thorens Box I have have Plays Metal Disks.
The Disks Have a Diameter of 4 1/2 inches.
I have about 12 Disks
It has a single Comb with 30 Teeth.
I mean it HAD 30 Teeth.
It now has only 27 because 3 teeth were broken off and are gone
The Comb measures approximately 1 5/8 Inches and is held down by 2 Screws

Underneath the Box you can just read the words

            Thorens     New Hyde Park

I hope you find something in your basement
If you need more detail, I could take a photograph and mail it in due course
Best regards

Charles Kossman
