This item is a Sargent knuckle joint block plane with a Stanley iron. The moveable part of the sole has one of the raised nipples broken. This raised part allows the adjuster to move the sole. The adjustment can still be made but not by using the adjuster. The knuckle has "SARGENT " stamped inside a rectangle on it. The moving part of the sole has "306" and "316" cast into it. The iron is a Stanley part with "STANLEY NEW BRITAIN CONN. USA" stamped into it. All parts are free of rust, iron is good just age patina.
