Exactly the sort of response I was looking for, John. Thanks much.
You'll see that I already cross-posted to G-R in hopes of more information. She knows the taping date (June 23, 1974) and believes that it aired either on July 9th or 11th. Her aunt's name is Pat Corral, she played (and won) 'Give or Keep' and went on to win her Showcase (Good Humor Bar, Chanel Perfume, Fur Coat, Opal Car) with a bid of $4200. It sounds like she'd already made some sort of effort to reach someone at CBS, but I got the impression she didn't know what she was doing. The fact that she e-mailed ME of all people, given so many more folks who know TPIR ins and outs better than I do, also shows she's sort of grasping at straws here.
