Unfortunately I don't believe the original First Aid Kit is available anymore. I ended up buying a new kit and for the sake of originality I replaced any dried out and damaged parts with the same component from the new kit. Labeling has changed slightly but otherwise the actual components are the same.
If you do find a source for the original kit let me know as I'm also interested.
