Everybody knows what a Stanley knob looks like, but, I have a couple knobs that AREN"T by Stanley. First off, the "typical" stanley knob:SDC13341.jpgand then the two "other" knobs I have:SDC12971.jpgand the other..SDC12970.jpgneeds some finish on it. Almost like the knob on a dunlap block plane I have..SDC13019.jpg The unfinished knob is on a DE block plane, maybe a Sargent made plane? That other "mystery" plane??? Not one mark, anywhere on it. The Dunlap has all kinds of markings on it.. The first one? Is a Stanley #110. The two planes without an ID are both about 1/2" shorter than the 110. Ideas, anyone??
