The manufacturer of the theodolite is the Urals Mechanical and Optical 
Plant, situated in Ekaterinburg (formerly Sverdlovsk) in the Urals, Russia. 
The type of theodolite is the 3T2KP. They are very much still in business - 
they employ 20,000 people! See http://www.airshow.ru/expo/304/prod_25.htm

I too have one of their theodolites, a type 2T30P, which was given to me in 
a ruinous, non-working state by a French friend. I took it to bits and 
restored it to back to health (not a project to be undertaken lightly!) and 
it now works very well. I made some attachments to illuminate the scales 
and the cross hairs in the dark, so that it can be used to measure star 
altitudes. Also a solar filter for the front lens using two glass neutral 
density filters totalling 5.0. (My retina is still fine...) to enable me to 
measure altitudes and azimuths of the sun. It only reads to five minutes, 
though the scale is large enough that it is easy to interpolate to one 
minute, and the telescope is 30x so it is easy to measure to one minute. 
But its great asset is its weight - just two kilograms (four and half 
pounds) so lugging it around the Scottish countryside to survey prehistoric 
stone circles is not a problem.
