Lietz Sokkisha TM-1A 1-second optical theodolite in its original orange heavy-duty case with carrying strap. SN 2144. Once owned by National Oceanic and Atmospheric Administration (NOAA). This is an amazingly fine piece of surveying equipment capable of 5 to 10 minutes of accuracy. It is in pristine condition, all parts on the theodolite appear to be present and functional, but you may want to have it professionally serviced before putting it to use. Comes with a tubular sun shield, a lime-green plumb-bob, and a small accessory kit containing two light bulbs, a small screwdriver, and two small adjustment tools. A marvel of geodetic engineering. See photos for condition details. State: City: Date: Provenance:
