But so did Geoff's later pieces. If it has larger letters it could be Jason or Geoff, there's no way to tell. Just try the mouthpiece and buy it if you like it.I think the geoff lawton pieces have the words and letters in a small font, and the newer jason lawton pieces use a large font.
BTW, at one point I understand they were making mouthpieces together, so even if you could date the piece, it wouldn't tell you anything.
