Two local museums (The Whipple museum for the History of science in Oxford, UK, and the National Maritime Museum in Greenwich,UK) list sextants mounted on pillars among the objects they possess. They are not "pillar sextants" of the double frame type, but clearly not for use on board. So it seems they are a special type intended for surveying on land.

Is it possible that someone confused a surveyor's sextant (mounted on a surveyor's staff or Jacob's staff) with a "pillar" sextant?
