All clips show the moment that the wrestler in the receiving end reverses the position, and then applies the headscissors. I also appreciate the victim struggle to get rid of the hold and sometimes achieving that.
The one below is not the best secured hold I ever seem, but the wrestlers (from TPC Video) are so sexy dressed that I have selected it.
The one below is from Golden Girls and show the victim escaping and getting trapped again and again.
The following is a classic pro-match, very likely from Mildred Burke. A funny thing to notice is the fighters awareness of the camera position, moving around on the mat to deliver the best view to the watchers as the hold evolves.
