Unit winds up and functions as it should. It ran for 5 days straight, I didn’t wind it all the way up, and it rotated the paper as it should. I don’t know about any of the calibrations. Looks adjustable. Window shows mechanics working when engaged. I don’t know how the needle writes, if you need to add lead or what. Very clean in and out. Photos of exact items being sold.
