This Leica M1 with the Zeiss medical device has been used for many years in a childrens hospital in the Netherlands. The Zeiss add on is in Mint condition.
Overall the camera is in great condition. On 2 places some vulcanite camera covering is missing Please have a look at the pictures. Otherwise it is in near Mint condition.
The shutter speeds seem to be accurate. I did not test it with professional equipment though.
It comes with the camera cap.
