...Or can anyone tell me if this sort of theodolite would have been used on trig points? http://20thcenturyprops.co.uk/69/1000-M ... d-P81.html

Hello,

I am in desperate need of a trig pillar expert to answer a few questions for me about theodolites. we are going to filming trig points for a new channel 4 series next week and I am in desperate need of some information i can't seem to gain from google.

If you would be happy to help, please ...
