Greg you're probably right, I've no way of telling to be honest. In terms of wear, no it hasn't got any snuff in, yes it is damaged quite considerably (though I don't think that counts as wear lol) and yes the glass looks seedy, a bit dirty in the clear glass make up as it were (the bottle is scraped inside as well, I don't know what that means though as it could have been done deliberately I guess).
I've put a couple of closer up pics on.
