I am studying about North Atlantic tracks. I know the message is usually distributed to interested parties via AFTN and is published by Shanwick or Gander. I would also like to get such information from the same source.

Where can I download NAT Track Messages in their original format (I guess it is the AFTN Message Format)?

Note: I want the official and original message possibly. I don't want other websites that show me NOTAMs or other formats that are not official. I am interested in the original message.
