Commentary:
This theodolite is emosed with ” E.R.WATTS & SON LONDON 4933″
It is similar to a geodetic theodolite that is shown on pages 16 and 17 of an E.R. Watts and Sons Limited catalogue published in 1910. Two models were available, one with a 10” circle, the other with a 12” circle. Both were advertised as reading to one second and being “packed in two strong teak cases for transport.”
Used by Geodetic Survey Canada, for geodetic survey observations.
In fair condition, does not rotate freely on horizontal axis.
