Most people do not know these chips because they aren't very easy to come by. I don't think many were made..
A few months back on the TH-P forums a person (Nate PT??) got some chips from TR King that were being sold at a discounted price because of a manufacturing defect that meant they just needed to be cleaned up a little, then they would look brand new. So, once he posted this info, myself and several other forum members ordered chips and I think eventually took all of the remaining chips. The price was great for some nice TR King chips.
Pictures are at the link below, I don't think they were ever sold at that price, though.
