I finally bought a Stanley 140 off of E-bay after six months of trying to get one at a decent price. I wanted something to "tune" wide tenons and it looked perfect (I already have a stanley 92 for shorter tenons). I sharpened and honed the blade and it finally hit me when I tried to use it. The right side of the plane comes off to expose the edge of the cutter. That means I have to trim the left end of the tenon or pull the plane towards me with the right hand. This is all wrong for a right handed person. I guess I'll look at the LN rabbet block plane now.
