AMSI Miniatures Ornate Spiral Staircase Kit AMS-15=10 112 Scale 1979 Mint
This is a professional-grade, 1:12 scale "Ornate Spiral Staircase Kit" manufactured by AMSI Miniatures (San Rafael, California), part number AMS-15. This high-end architectural kit is designed to create a 10-inch high spiral staircase. The components are crafted from heavy-duty cast metal (pewter or white metal) and feature intricate, period-accurate filigree detailing on each step and baluster. The kit is engineered with a central support column design, allowing for precise installation in custom dollhouse builds.
CONDITION: The item is in Mint condition. While the original cardboard storage box shows significant age-related staining and wear, the internal cast metal components remain in pristine, "as-new" condition.
All individual steps and the central support rod are present and show no signs of oxidation or damage. The original instructional header card and assembly diagrams are included and remain fully legible. HISTORICAL CONTEXT: AMSI Miniatures was a prestigious supplier of architectural dollhouse components in the late 1970s and 80s.
Their cast-metal kits were renowned for their superior weight, durability, and realistic detail compared to cheaper plastic alternatives. This 1979 kit represents the "premium tier" of the miniature hobby market during its peak, offering builders museum-quality Victorian-style hardware that was manufactured in the USA. APPRAISERS NOTES: In the miniatures market, cast metal spiral staircase kits are high-value architectural anchors.Because these kits are no longer in mass production and the casting molds for this level of detail are expensive to replicate, they are highly sought after by professional dollhouse restorers. The significant weight (1 lb 6 oz) is a primary indicator of its quality and authentic metal construction, which drastically increases its Fair Market Value over modern resin copies. VALUATION REASONING: The Fair Market Value is determined by analyzing realized prices for vintage AMSI cast metal kits on specialty hobby platforms and estate auctions. While modern plastic staircases sell for under 40.00 dollars, verified vintage AMSI metal kits in complete, unused condition typically trade between 85.00 and 125.00 dollars.
The valuation reflects the rarity of finding a complete 1979 "AMSI-15" set with original diagrams. ORIGINAL MSRP: 34.50 (Estimated 1979 price). FAIR MARKET VALUE: 110.00. Be sure to add me to your favorites list! Check out my other items!
