This is a remarkable vintage precision measuring set by the renowned Brown & Sharpe Mfg. Co. of Providence, Rhode Island. The set includes two high-quality steel vernier calipers of different sizes, beautifully preserved in their original fitted wooden presentation case. Also included is the original instructional booklet titled "The Vernier," offering a fascinating glimpse into mid-century machining history. The wooden case features a rich wood tone exterior with gold-leaf branding on the lid reading "BROWN & SHARPE MFG. CO. Providence, R.I., U.S.A." The interior is lined with a deep purple velvet or felt, custom-slotted to securely hold each caliper. The calipers themselves exhibit the exceptional craftsmanship Brown & Sharpe is famous for, with clear, legible graduations and smooth adjustment mechanisms. This set is in very good vintage condition. The wooden box shows minor surface wear and scuffs consistent with age and workshop use, but remains structurally sound with functional latches. The calipers show minimal signs of oxidation and retain their precise alignment. This is an excellent addition to any collection of antique scientific instruments, machinist tools, or industrial Americana.
