Vintage Simplex Time Recorder Clock (Tombstone Style)
Clock turns on when plugged. The stamping is lever operated but I don't have ink to test. (Does not come with a key)
I have spent quite a bit of time researching, trying to find details on this specific model but I've only ever seen one picture(on Google) that matches the one I have listed. All other's don't have the lever.
Please let me know if you have any questions.
