Vintage Drafting Instrument Set in Velvet-Lined Case

This item is a vintage set of drafting or drawing instruments housed in a black, possibly leather or faux leather, hard case with a vibrant green velvet interior lining. The case appears to be in good condition externally, showing minimal signs of wear. The instruments themselves are constructed from a silver-toned metal, likely steel, brass, or nickel-plated brass, exhibiting a polished or satin finish. The set includes various compasses and dividers of different sizes and designs, some with fine adjustment wheels for precision. One larger compass features a 'C' shaped handle, designed for comfortable manipulation. Another smaller instrument appears to be for pen or pencil attachment, indicating its use for inking or drawing lines rather than just inscribing. There is also a small cylindrical capsule, likely for holding spare leads or needles. All instruments are neatly nested within custom-fitted compartments in the verdant velvet, preventing movement and protecting them from damage. The visible condition suggests that the instruments are well-preserved, with no obvious signs of rust, heavy tarnishing, or bending. The set likely dates from the mid-20th century, possibly 1950s to 1970s, based on the material appearance and common design styles of the era. The craftsmanship appears to be of good quality, focusing on durability and accuracy, typical for professional or educational drafting tools. This comprehensive set would have been essential for technical drawing, architecture, engineering, or geometry disciplines.
