Pre-owned Vintage Antique Pre-1920 Lathem time clock with leather case Outside key, NO Inside Key Also box of time recorder papers The only key I see missing is the key on the inside to open and change recorder papers I know nothing about it. Just a great conversational piece or Great for decoration. The key that is with it for the outside does make a click noise when you turn it. I also have other keys that I'm selling separately, if you need any or if you would like more for this machine. Thank you for looking!!
