Commentary:

The significance of the name “Tavistock” was always a bit of a mystery until a bit of research resulted in the finding that the name referred to the town in which it was designed. From a dated picture in a pamphlet accompanying the theodolite, it appears this instrument was produced sometime after 1936. According to C.H. Weir ALS#164, this theodolite dates back to when A.G. Stewart ALS#078 was in private practice in Edmonton..
