In Some states now, if you have your paper work/registration the State Game and fish dept. will make you one with a machine they have. You just take the ski and paperwork to them and they inspect and make a new tag for you out of stainless steel. They did that for me here in Arizona a couple years ago. But, yes there is a guy on here who used to make them, but i cant remember who or if he still does.
Good luck man!
