Cap thanks for the reply. I think one or two of the first one's I had made were marked so but maybe not. I would have to dig them out and look as I don't have my stuff inv. very well. I know that the first two that I got from Rick S. in the 3 set remember Vietnam were so marked but Rick said Gary did that as a favor. The third knife is not marked as I think Gary realized that it was taking to much of their time. I believe you can send one back and have it so marked for 35:00 if I remember right.
