Dating stanley plane blades
I've always used the term 'iron' to represent the chunk of metal you sharpen to make the plane a plane.
Stanley, in their reams of propaganda, referred to it as a 'cutter'.
There were some subtle differences in the dimensions, but only those that are significant are mentioned where appropriate.
Some of the bench planes are a bit longer/shorter, wider/narrower, heavier/lighter than what's noted for the fact that the planes used many patterns over their decades of production.
The earliest models have an I-shaped, or H-shaped (depending upon how it's viewed) receiving area for the frog.
Subsequent models have the broad and flat receiving area. A smooth plane, according to some Stanley propaganda "is used for finishing or smoothing off flat surfaces.
So, if you have a plane that's one-half inch shorter or longer than what's mentioned here, don't go thinking that you have some ultra-rare version of the tool.
As proof that they were used, they do suffer damage, primarily about their mouth.The quickest way to tell if it is a fake is by examining the threaded rod on which the depth adjustment nut (the brass knob) traverses.An original has its rod perfectly parallel to the sole of the plane, whereas the reproduction has its tilted upward toward the tote.The thinness, and consequent fragility, of the bottom casting makes this damage the most commonly found on these planes.A cracked tote is another fairly common flaw found on these planes.
