OK SO I READ THE MAMMOTH THREAD ON T-RAY & THE AMERICAN ARTS STAMP ON THESE FLANGES,I ATTACHED PICS OF BOTH SIGNS IN MY AREA THAT I HAVE A CHANCE TO BUY FROM A FRIEND & REVIEWED THE PICS I HAD TAKEN AWHILE BACK,AND DID NOT SEE THESE STAMPS,WAS THERE EVER ANY CLARITY ON THESE FLANGES AS FAR AS THE ONES WITHOUT STAMPS? I HAVE PERSONALLY HAD THESE FLANGES IN MY HAND,THE ONLY THING THAT STANDS OUT THAT I REMEMBER WAS THE PAINT "EXTREMELY BRITTLE"ANYWAYS BY THESE PICS COULD ANYONE CHIME IN ON THE AUTHENTICITY OF THESE FLANGES? THANKS!
