Quoted from rufessor:I find this too weird. Its not hard to measure to within a 1/16 th of an inch. How is it even possible that someone would spend the time to generate the art and cut the wrong size glass! Is it the case that originals vary substantially? Seems not unless they sat down with a pile of glass on the assembly line and sorted through until whichever one they picked up happened to work with the head on the production line. That seems unlikely....
So what gives? Amateur hour or expected variation? Just curious.
Amateur hour. The old carpenter saying of measure twice cut once applies here. I won't name names but one back glass make had to eat one because his contractor measured it incorrectly. And the art was on.
