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.
