Based upon a close exam, including a "burn test" of some loose material I am starting to doubt my original assessment. The burnt material smelled and burned like wool. Secondly, there is evidence of that excess piping that I mentioned earlier. (remains of stitching that would have bound the piping ends to the back of the tab). The only remaining question I have now is what the backing material could be. I am not able to safely remove a piece for a burn test. If anyone else has an idea how to identify material without destroying the tab, please let me know! At this point, I am willing to go with the assumption that these are now authentic until I learn otherwise. Please, if you find any other LW tabs you feel to be repro or fake please post them! Thank you Gene! Regards Paul
