I found the web site you were probably referring to: The Maine Music Box. Indeed, they have images of the cover and the first 2 pages of the music, then it breaks off in mid-phrase. There must be at least 1 (probably only 1) page missing.

I'm guessing that they HAVE the missing page in their library, but due to some mistake, they failed to scan it and/or upload it to their web site. Accordingly, I have emailed them. Hopefully they can correct this error. I will let you know if I get a meaningful reply.
