Thank you very much for viewing from among many items. Authentic vintage! This is an analog tachograph TCO-134-7F-120 made by Yazaki Corporation (YAZAKI). It's missing the key, but the lid is open. When the mainspring is wound, the red and white parts move, and it kept time for about an hour that I observed. Since it is a very old item, I will consider it as a junk item. How about it for decoration or display? Please purchase only if you understand that it is a used item. Thank you for your consideration.
