Vintage K&E Slide Rule Tie Clip - Kinney Co

BP94. Vintage K&E Slide Rule / Ruler - Kinney Co. So unique! Gold in color w/a white slide rule (enamel?) decor on front. Doesn’t have any moving parts. Esti 2 1/4”L. Unsure of exact age, believe 1950s-1970s. Please see pix. The clip is slightly askew, but still functions well. Stamped Kinney Co on clip. Some scratches/markings but decor is still quite bright. From estate of a long-retired NASA gentleman. More to come. Bundle your likes, can fit many items safely in a box to save on shipping.
