Dating stanley transitional planes
This type study is based upon Roger Smith's original and includes many comments and updates from Patrick Leach. "The improved form of this Plane Iron renders it unnecessary to detach the Cap Iron, at any time, as the connecting screw will slide back to the extreme end of the slot in the Plane Iron, without the danger of falling out.This information was originally on Jay Sutherland's website, but it went inactive sometime in 1999 or 2000. The screw may then be tightened, by a turn with thumb and finger; and the Cap iron will serve as a convenient handle, or rest, in whetting or sharpening the cutting edge of the Plane Iron." There you have it, in all its gory, why the circular hole was repositioned, after it being at the top of the blade for some 100 years. However, the patent drawing for the change shows what I believe is the real reason for the change - the circular disk, on the lower end of the lateral adjustment lever, loses its ability to engage the slot provided for it (in the cutter) when the iron is nearly used up.Hopefully by answering a few questions about your plane you can determine which type it is.The flowchart starts by asking questions about the cast iron bed of your plane.The Stanley ‘transitional’ planes, combining a wooden body with a cast iron frame, frog and standard adjustment mechanism, were made between 18.You see these things pretty commonly in antique shops and flea markets.Stanley claimed that "Every Carpenter needs two or more wood planes in his kit, for rough outside work" and that "wood planes push easier." Thus, these planes were offered as an alternative to the metallic planes.Furthermore, some guys preferred the feel of wood against wood, like that afforded by the old style wooden bench planes.
Thus, the plane's body could practically be any size desired.
Send them to me and I'll add them to the flowchart...) If you find errors or discrepancies, Patrick's Plane Type Study is the final authority.

This stuff is applicable to all Stanley bench planes of the basic Bailey design (as well as those that incorporate the Bailey patents such as the Bed Rocks), and comes from my observances of thousands of these planes.
All dimensions that follow each number indicate the length of the sole, the width of the cutter, and the weight of the tool.
