Wed. J. Ahrend & Zoon
Although not an instrument manufacturer, but a trade-firm in office
furniture and supplies, Wed. J. Ahrend & Zoon (or Ahrend in short)
is still worth mentioning. Here in the Netherlands they were the
major re-seller of geodetic instruments of all sorts, like survey
tapes and chains, surveyor's crosses, sounding and geodetic
sextants, levels and theodolites. Among the firms they featured were
De Koningh and Wild
Heerbrugg.
This instrument is similar to a 1965 Wild
Heerbrugg NK01 - See:
