Wild Heerbrugg NT2
Wild Heerbrugg NT2. Obtained from Hungary.
Second model of the famous T2 theodolite. The NT2 differs in many ways from the original T2. It is very similar to the T21 but differs from it in that it has a 'knob' to rotate the bubble reflector. I have two of these at the moment, one from Belgium, one from Hungary.
The Hungarian one example was used in the Hungarian cartographic office where they were to be scrapped. The father of the hungarian whom I bought this from saved the instrument but unfortunately stored them in his attic. The instrument is now in a terrible condition and will require a complete overhaul at some point in time. It has been in a damp / wet environment for long and is rusty to the extent that the focus ring is stuck. Paint is missing and is starting to blister due to corrosion under the paint. The glass scales are unreadable due to (hopefully...) dust. What made me buy it was a) I do not have a NT2 yet and b) it came with most of the original accesoires.
In particular it came with the brush to clean it, a bottle (probably used to contain oil) ánd two right angle prisms for both the microscope and the telescope. I have a newer set for the T21 / T16 of these but those differ in that the telescope prism for the NT2 also has a coloured shade potentially allowing it for sun azimuth. No use in trying it untill it is cleaned though...
The second NT2 that I have was obtained much later from Belgium. According to the inscription it belonged to an 'André Denamur' from Bauffe, who was a civil engineer. Unfortunately I have not been able to find much more information. This instrument is, optically, in a decent shape. However, the previous owner has decided at some point in time to make the operation 'dummy proof' by painting various surfaces with a colour. The reason for buying it were the accesoires that came with it. Attached is a Horrebow level as well as a telescope level. The former is very rare, the latter reasonably rare (I have two others attached to instruments). The Horrebow is especially interesting as it also has the attachment for my horizontal striding level, making it a full astronomic theodolite togehter with the eyepieces that came with it.
