Keuffel & Esser (K&E) surveying transit, model P5137, SN 136307, in its original wooden carrying case. This is a precision piece of optical and mechanical engineering, and at one time, it was a mainstay in the surveying industry. Made to be mounted on a large tripod. It appears that all the pieces except the lens cap are present. The optics are complete, the compass needle hangs freely, all the spirit levels are intact and working, and all the knobs that should turn do so smoothly. You could put this to work right away or proudly display it in your home or office. State: City: Date: Provenance:
