Bob - is that description essentially the top and the bottom of the bathtub if you turn the head upside down?
Tony - I suppose I was just seeing if anyone had measured or compared a non tap LC head vs a tapped one vs a pre1933 already before I try and look! I see its ambiguous, but it seems plain that a big "mineshaft" in the corner of the bathtub must be responsible for something of a reduction, so unless they did something else to counteract - like make the head taller - the CR must have risen at exactly that point of their removal...?
