Vintage 4" tall heavily embossed metal emblem/sign that went on a Buff transit. Transits are the large surveying telescopes set up on tripods. Buff manufactured some of the highest quality in the industry, and these emblems are indicative of that. They are very detailed. The embossing is so deep that they look three dimensional. Incredible detail. You can see all the bolts and parts on the telescope pictured. The backs have two copper wires that were used to attach them to the transits. Circa 1930s and still unused in their original envelopes. Excellent condition. They came from the estate of the famous dealer and friend, Bob Secrist.
