Antique19thC Physics & Scientific Instrument Trio - Featuring a fascinating trio of 19th-century scientific demonstration instruments, this lot is a true treasure trove for early physics and electrical enthusiasts. Included are two antique electrostatic hollow conductors used for physics demonstrations—one featuring an insulated glass pedestal base with a dark metal footing supporting a polished brass T-bar cylinder, and the other featuring a glass globe chamber housing a metal-leaf style electroscope or spark gap element, topped with a cylindrical iron T-bar. The third piece is an intriguing early architectural model: an antique Boyle's Patent Ventilator, featuring a decorative cast iron base, a long glass tube riser, and a patinated metal lantern-style cap proudly stamped with ”BOYLE'S LATEST IMPROVED PATENT.” These historic instruments show age-appropriate wear, including tarnish, surface oxidation on the iron components, minor scuffs on the bases, and a light accumulation of interior dust within the glass chambers, though the glass elements remain remarkably intact without any major cracks or deep chips.
