Surveyor TransitBeckmann W&LE Gurley Complete

Everything seemsto be complete, glass is clear and all is in working order. This transit wasgiven to me by my late step father. He told me that he used it in the early40\'s. According to the label it appears that it was last serviced on 6/70 byThe Beckmann Co. I was not able to find a serial number, model number or date,only inscription that I see is W. & L. E. Gurley. I am selling it completewith transit, tripod, marker stakes and pins.

Please let meknow if you have any questions. Thanks.
