Question about (seemingly) uncredited cast member

Maybe I somehow missed her in the cast list here on the IMDb, but I can not figure out who plays the female office assistant who shows up just after the 96-minute mark, hands Charles Lane some copy and tells him, "Here's that Women's Federation story."

She's middle-aged, but well-built, long hair that could be grey, great bone structure...does anyone here know who she is (was)? She just really stood out to me (she's ten times as sexy as the vastly overrated Mamie Van Doren, I think), and I wanted to see what else she might have been in, if anything.

Thanks for any help anyone can provide.
