Every time this topic comes up it's the same thing. Those thundering that only the original will do and those who disagree. You could have a photo of the original, or a rusted out original tag, and there are those who would not accept a duplicate tag using either of these as guidance. My thought, if someone is thinking about a reproduction tag, do it and don't tell anyone you did it. 95% of people can't tell the difference and the other 5% are too damn close.
