Scientific Precision, Historic Optical Marvels, and Rare Coin-Op Treasures Unite in an Unforgettable Event

Step into an extraordinary showcase where centuries of groundbreaking innovation, artistic craftsmanship, and mechanical wonder come alive. Featuring premier selections from the distinguished Dale Beeks, Allen Koenigsberg, and Howard Hazelcorn collections, this curated auction presents a captivating journey across the frontiers of early science, visual culture, and vintage entertainment.

The catalog spans an exceptional breadth of rare material. Precision scientific and surveying instruments anchor the event, highlighted by 19th- and early 20th-century brass theodolites, transit levels, maritime sextants, and research microscopes from master makers including Bausch & Lomb, Cooke, Troughton & Simms, E.R. Watts & Son, and Keuffel & Esser. Early visual media and pre-cinema wonders abound, offering cased daguerreotypes, rare daguerrian maker tokens, ambrotypes, magic lantern slides, zoetropes, and classic stereoview collections. Collectors of technical and industrial history will find early electrical and medical equipment—ranging from historic electrotherapeutic cabinets and quack medicine devices to telegraph sounders and antique carbon-filament light bulbs. Rounding out the lineup is a vibrant selection of vintage entertainment, anchored by antique Seeburg and Wurlitzer coin pianos, historic theater architectural elements, and vintage advertising.

These artifacts embody an era of relentless exploration and brilliant ingenuity. Every hand-engraved brass scale, silvered photographic plate, and intricate gear mechanism carries the spirit of the pioneers who mapped uncharted territories, preserved fleeting moments in time, and brought automated music to lively parlor halls. For everyone devoted to Chasing History, this event offers a rare chance to own tangible milestones of human progress.
