There are probably more than this and I'll add them as and when.
In regard to when are they original and when are they copies; well I would say its all about the angle of the collar zip and about counting the rings round the neck, knees and arms. I would also watch out for the shoulder ring because when that's gone, I reckon you're looking at a inspired-by copy. Let me know what you think.
