2797. This is a surveying instrument that was patented in Great Britain in 1946, here is one of its uses as described in the patent:
"One problem which frequently arises and which cannot be efficiently solved by other instruments is the production of straight lines over undulating country such for example as the determination of a point on the top of an embankment in line with two points on either side of the embankment. Holding the instrument with the axis of the pivot horizontal and the mirrors set at a convenient angle, the user moves to and fro on the top of the embankment until the close relationship along one edge are adapted to be set at an angle to one another with their planes intersecting, a guide line being provided on each mirror at right angles to the axis of intersection, the guide lines being in the same plane."
