That whistle sounding wind up toy that rises in pitch has been built by a couple locals around here (the Columbus area) over the years. There are probably others out there as well, but I know of two that build the one heard in your youtube videos. (they called it a Spacebird) The last one I know of that sold those was Roadstar 188 (I know because I helped him with the switching circuit to make it key up with the MIC PTT instead of push button).
However, these have not been built or sold for a while last I recall, at least the last year and a half maybe 2 years, He has been pretty busy. So if any were purchased recently, I’m not sure who it would be.
Noise toys can be fun to play with occasionally, but I don’t use them otherwise & have not been interested in them in several years. I generally do not mind hearing them, though some can be quite annoying after a while.
