Collimator for transit instrument
Collimator for a transit instrument. Consists of a rectangular metal base on which a lens in a metal frame is attached at right angles. Behind the lense is some sort of lever, behind which is a round metal disc with a square hole in the centre and screws (to hold something in place over the hole?). Below the hole is a lever to bring a mirror closer to the hole.
