This is a very unusual Magnetic Dip Needle or locating Compass. It was made by Municipal Instrument Company of Berwyn Illinois. It was used for locating metal objects underground such as manholes, water valves, curb stops or property irons. Surveyors could use this for locating metal property or survey markers without bending over. It is carried low to the ground with the needle to the North. Since it is basically a compass, it is easy to find North. It could also be used in mining for tracing veins of heavy metals by variations they cause in the inclination of a local magnetic field, the same as a man hole or property iron marker. It is made of a lacquered brass with a glass window and extendible handle. The face is 3-3/8" inch diameter, 1" thick 13-1/4" long when retracted and 29" long when extended. The face has silvered standards, holding the red & white needle. The face reads from 90 degrees to 0 degrees from bottom to side on both ends. It is graduated every 2 degrees on a paper scale which has come loose ( see photo), but could easily be reattachaed. The glass on one side has a crack (see photo). The overall condition is excellent showing good patina. When the pin on the chain is removed, the needle is released and the handle extends. The box is made of wood with black cloth covering and velvet lining and no lid. It was made in the early 1900's. Please check out my other antiques for sale in my store. Combined shipping available.
