Item Description
Up for sale is a rare, premier-grade vintage 1930s Holland Furnace Company Model No. 250A salesman sample furnace set. This miniature demonstrator was carried door-to-door by sales representatives in the early 20th century to showcase the company's famous warm-air "octopus" heating systems directly to homeowners in their living rooms.
What makes this specific unit an absolute grail piece for industrial Americana and advertising collectors is its functional condition: the internal electrical components are fully operational. When plugged in, the interior lights up (simulating coal fire ignition) and the miniature electric blower fan actively runs to demonstrate airflow through the venting ports. Most surviving models are completely dead or heavily damaged, making a working model exceptionally rare.
This remarkably complete collector's set includes the cast metal/aluminum miniature furnace body, its original dark travel carrying case, and the incredibly hard-to-find Holland Furnace Co. Aluminum framed instruction sign insert.
Condition Details:
• Electrical & Mechanical Condition: Fully functional. The internal motor runs smoothly, air blows from the vents, and the interior illuminates beautifully.
• Cosmetic Condition: Excellent vintage condition showing a beautiful, authentic patina. The doors open properly, and the embossed metal text ("250A HOLLAND") is sharp and legible.
• Carrying Case & Sign: The original travel case shows normal exterior wear from age and historic use but remains structurally sound with its functional handle. The background aluminum framed advertising sign remains intact with clear graphics and text.
Please review the high-resolution photos carefully to assess the exact cosmetic condition. This is an incredible, working museum-quality piece of industrial advertising history.
