Surveyor’s Theodolite European

Surveyor’s Theodolite European. Made in the 20th century. Very fine, steel and brass surveyor’s precision theodolite with compass and fitted wooden travelling box. To be sold without reserve Notes Instruments with 8" scopes are usually called « Light Mountain » or « Preliminary » transits. The transit as the theodolite was first called, was developed by William Young in the early 19th century. He incorporated the standard surveying compass with surveying levels and scopes in one instrument to equip the surveyors who were charting the American territories. The first transits were called theodilites, the definition of a theodilite has changed over time with more precise instruments being called by that name today.
