Sources: While many of the dealers prices for Stanley planes are largely set by John Walters’ book “Antique & Collectible Stanley Tools” it appears that eBay, while acknowledging the Walters guide somewhat, tends to march to it’s own beat and sets its own prices. For that reason - and the fact that eBay’s reach and customer base is huge - I’ve decided to include a separate eBay average price here. Other sources include: “The Antique Tool Collector’s Guide To Value” by Ronald S. Barlow, “Antique & Collectible Stanley Tools” by John Walter, “The Stanley Plane” by Alvin Sellens, “Patrick’s Blood & Gore” by Patrick Leach, various auctions and sales of collectable tools and my own compilations of prices realized, observations and notes over the past 20+ years.
