KERN SWISS MADE AUTOMATIC LEVEL VINTAGE SURVEYING IN INDIA

T his is a Vintage Kern Automatic Level used for survey purposes. All the dials seems to be working but i have no idea how it actually used. The instrument is Swiss Made and also has 2 working Spirit Levels built into the Solid heavy metal construction of the body. "MADE IN SWITZERLAND" is written on the top. Has a tripod mount socket at the bottom. Looks like a well made Swiss Mechanical engineering wonder. Great collectible, also may be working. The degree scale seen below the viewfinder is also working. EXTRA PICS BELOW PLZ CHECK
