I'm pretty sure its these older dolls.
Also the surfaces are sandpaper like, not smooth as seen in the magnified view of the white straight track in https://postimg.cc/nCkhTBMr. Not sure if the Merry-Go-Round is smooth, most probably yes just like any other gimmick rail during that time.
For sure the whistle is missing, but I don't see how the whistle functions in the set. Probably just a prop whistle.
