In email exchanges with Jerry, he informs me that he's sold some blems but was surprised that they weren't moving as fast as the production run.
Jerry is a perfectionist and to him the tool must be absolutely perfect to be a production run item. They had a run with some machine marks, hard to see without close scrutiny.
This photo shows a blem and a perfect production piece. I can't tell the difference and he says one has to hold a unit up close to tell the difference.
I think the price break on the blems represents an opportunity.
BTW, the "blem" is on the left.
