Ryan, I had thought the way the other member here spoke of his mark it may be a luft mark. Since its not posted i dont know. However the mark you speak of and the one I have shown is not a luft mark. After re-reading this again I worded the whole thing a but goofy(thats me sorry!)but not a luft mark. just a diffrent zella factory mark, as far as I know.
