My script which I thought was the original ends with Wendy leaving neverland on a broomstick.
You might have the version I have, which is the 1928 published version--that's considerably different from the original 1904 version. I don't know much about it, but from what I've heard, most of the changes made toward the story as we currently know it were done after that first year, so by 1905. After that, though, he continued to tweak it (mostly to Hook's soliloquy at the beginning of the pirate ship scene, which didn't originally exist) until he published it in 1928.
I don't know much about the 1904 original, but it didn't have the Mermaids' Lagoon scene, and it had Peter's goat, I think, and the "20 Beautiful Mothers" scene....
