surveyor's Y level
Made in brass, this instrument comprises a telescope, a spirit level and a compass. The telescope is supported by a Y-bracket, from which the name Y-level comes from. The telescope can be removed from its support and turned back to front to make measurements. In the field, this surveyor's level was mounted on a ball-and-socket joint, parallel plates and four leveling screws, which was then attached to a mahogany tripod. A small wooden circular base has been built in 1976 to display the instrument itself without the tripod and other field accessory.
