which heirloom could this be?

[kchd..]

I had a conversation yesterday with a colleague about tomatoes. He is getting back into growing them after many years of not having done so. He said he used to grow an heirloom tomato about 20 years ago when he lived in Missouri that he liked. He couldn't remember the name, but he said it was pink and had the word "blush" in the name. Any ideas?

If any resource could help figure this one out, it's going to be the Tomatoville community.
