How old is my Kern & Co. AG Aarau ?

Dating of Kern instruments is sometimes difficult because of two mainly reasons:

  • pre 1900, instruments like levels and theodolites did not have serial numbers
  • on drawing sets, they also used old items with old logos in newer sets (I have a set where they used logos from three periods ...)
So if your instrument has a serial number I might be able to tell you the approximately production date.

pre 1900:    no serial number (first registered serial number is 16615 from Jan.16. 1899)
    1910        19500
    1920        23500
    1930        27500
    1940        30500
    1950        40000
    1960        73000

If not, you might use the following overview over there company logos to date your instrument:
