AppleScript Email Extractor - missing script

I was going through some of @MacSparky’s older Youtube videos and came across the one where he describes the AppleScript used to extract information from an email in Apple Mail. I wanted to dig into it more but my AppleScript skills are pretty pitiful so I wanted a place to start. Unfortunately, the script is no longer available or no longer linked. Does anybody have the script handy? Otherwise I’ll just piece it together from the video but hoping to avoid that.
