And here you thought routers are the stuff of the modern workshop. They've been around much longer than the ab NORMal kind has, but these kind ain't the 'lectrical kind.

Start by reading Patrick Leach's comments on Stanley plane dating. If you thirst for heaps of data on plane dating, visit the Plane Type Study or the Plane Feature Timeline. This page leads you down a hypertext flowchart to determine your plane type.
It includes links to Patrick Leach's original Plane Type Study and the Plane Feature Timeline.
& please include pictures of the tools that you need parts for.
Planes, Scrapers & Spokeshaves, and other tools have threaded parts have proprietary & obsolete threads and are not available in hardware stores. To assist you in supplying the right parts for specific models and vintage tools, please provide me with pertinent physical details: markings on the tools -patent dates, trademarks, etc.
The format used for the type discussions and trademark designations generally follows other published studies. This is the Type Study part of a larger paper of 8 pages that also discusses the history, development and characteristics of this, the best plane ever made. See Beds marked with Bailey model numbers, No.2 to 8.
All sizes in production including those with corrugated bottoms. The listing does not include the No.605-1/4 (see note at Type 7), but does show the No.602-C as being available, which contradicts the assumed 1918 end of production for that model. Allow time for the page to download, as the image is large, in order to maintain some kind of readable quality. I recently obtained an original copy of a 1923 Stanley promotional pamphlet which illustrates and describes the Bed Rock Planes in production at that time.NOTE: This type discussion, along with the foregoing material, is based on personal examination of numerous Bed Rock specimens since 1973. Frog & bed machined & mated 100%; inclined frog seat. Keen Kutter Bed Rocks had plain lever caps and Winchester Bed Rocks had Winchester marked lever caps.Many specimens have been seen, but there is always the potential for finding a new type or an anomaly. In addition, most items are described with remarks in respect to percent of original finish (including re-paints); pitting; chips; breaks; repairs, owner's marks; missing, replaced and/or non-vintage parts, etc.
