Instrument	:	Theodolite (cercle d'alignement)
Manufacturer	:	Société des Lunetieres
Country of origin	:	France
Manufacturing year	:	April 1869

I've obtained this theodolite on a trip to Egypt in 1994. The instrument is of French origin and was used for simple measurements, probably in construction works. As it lacks a vertical scale it might be better to call it a cercle d'alignement (alignment circle)[GM].

The instrument was manufactured by the "Société des Lunetiers" in its manufacturing plant called "La Compasserie".
The vernier gives a precision of 1/30th of half a degree (1 arcminutes).
