I have an original Cordes Lambert Deluxe set of strings still laying around. I believe these were the second version they came out with prior to the wound sets, though I'm not exactly certain. They definitely are the "deluxe" version of the spiral cut weedwackers. Complete set of imitation raw gut basically. The picture is from the web. I don't have the cheese box they came in. I gigged these for about a year.
