I converted the type study to hypertext and added the plane dating flowchart and feature timeline.Stan Faullin helped by providing some of the pictures used in the Plane Dating Flowchart, and Steve Turner provided the Post Script version of the flowchart.
Four categories seem sufficient to describe and roughly date a plane: Pre-lateral for any plane that has no side adjusting mechanism for the cutter, low knob, SW model or tall knob (SW stands for Stanley Works but is usually called Sweetheart) and late models for WW2 vintage and later.
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.
By relocating the circular hole toward the bottom of the cutter, the iron can be used right up to the slot, without sacrificing the advantage gained from the lateral adjustment lever.
The chart below provides a brief summary of the key distinguishing changes identified in Roger Smith’s widely publicized Type Study of Bailey Iron Bench Planes and my own research over the past several years.
I've converted some of the plane dating information found in Patrick Leach's Plane Type Study into an easy-to-use hypertext flowchart.
Hopefully by answering a few questions about your plane you can determine which type it is.
Some were showered with attention by their former owners, others suffered the worst possible abuse.
Some owners worked them so hard that they had to replace one or several parts.

Frustrated at this, I began a quest two or three years ago to identify the major changes in the design and production of Stanley’s premium block planes, with a focus on the no. Rather than try to create a formal type study, I decided to focus more on the practical goal of simply establishing criteria for dating the planes within the narrowest possible time frame.

While there are still some gaps and inconsistencies across models (some of which appear within the published type studies of the nos.
