Dan,

You are correct...I guess it was misleading to have it in the Antique Surveying instruments album. I did not intend to mislead anyone.

This is no antique surveying instrument; it is a WILD T4 high precision theodolite used for I-st order angular measurements.

Thank Mr.David for the information :)

Mohammed,

The theodolite (also known as a transit instrument) is used to site stars for the purpose of determining latitude. (With a chronometer or radio time clock both latitude and longitude can be determined .It can determine latitude to 2 tenths of a second of arc, azimuth to 3 tenths of a second of arc, and longitude to 1 one hundredth second of time. The wires shown in the picture are for lighting the crosshairs for nightime use.

Tubo cenital.

Mohammed,

The Theodolite is a :"Wild T-4".  It will measure horizontal angles to 1 tenth of a second of arc and vertical angles to 2 tenths of a second of arc!!  It is called a "broken telescope type" because the eyepiece is through one trunnion and at a right angle to the telescopes line of sight. Because of its powerful magnification, it cannot focus any closer than 100 meters. It is considered one of the best theodolites ever made, and also one of the best geodetic surveying instruments. While designed to be fairly easy to use, most boundary line surveyors would need to be taught how to operate it.
