Since 2005 the innovation factory is part of Hexagon and more powerful than ever.

This is what we later came to know as WILD, WILD-LEITZ and Leica Geosystems. In 1921 the “Heinrich Wild, Werkstätte für Feinmechanik und Optik” was founded in Heerbrugg, Switzerland. A 1978 commercial photograph of the the Wild Heerbrugg TC1 total station In this article, Thomas Harring, the current President of Geosystems, takes us back in time. It’s the home of WILD, Leitz, and Hexagon Geosystems. If it is originally Wild I do not know, but it does fit a T16 canister nicely.In 2021, the Heerbrugg innovation factory in Switzerland celebrates its 100 year anniversary. The leather case was obtained separately from the UK. I have now fitted this theodolite with a circular compass which I bought together with another T-16 from the US. The tripod unexpectedly turned out to be the real catch as I did not have this model in the collection yet. The bracket ultimately did not fit the DI10, my guess is now that it went with an Aga Geodimeter which I do not have. The T-16 is slightly different from the Canadian one and indicates that the older designs had variations (notably the mirror on the vertical level is smaller). After some discussion I could even get the tripod shipped expecting that to be one already in the collection. I was not looking for another T-16 but saw this on a website with a bracket that looked like it would fit my DI10. The other T-16 comes with a similar story. The bracket for the GAK10 is mounted on top of the instrument, and the tubular compass is used for roughly aligning the telescope with (magnetic) North so that the gyrocompass can be run properly. It did come at a price as it is a very bulky instrument. The GAK10 is a rare instrument and as I only had a new T16 at that time I had to buy it. The T16 from Canada came with both the tubular magnetic compass ánd the GAK10 gyrocompass and all accesoires.

Both came with compasses although of a different nature. I do not make it a habit to keep double instruments in my collection but in this case I felt I did not have an option. The T-16 did however come with many accesoires of which many also fit on the T1 and T2. But that does come at a price (accuracy). My guess for its wide use in the army would be that it is the only theodolite from Wild that is direct reading (both vertical and horizontal scale can be read at the same time) avoiding confusion. It is just about as accurate as the much smaller (and more practical) T0. To me it does not make sense as it is the same size of the T1 and T2 but not as accurate as either of these two. It was however used extensively in the US Military so must have had a purpose. The T16 is, together with the T12, one of those instruments from Wild Heerbrugg that does not seem to make sense.
