If you are looking for Heinz 1439 here are some reviews I found.

I have not grown this, but it has been around for a long time, prior to 1963. Like many of the other Heinz cultivars it is a determinate with good production, disease resistance, tough skin and large seeds which should make processing easier. It says it is only slightly sweet and a bit tangy. Good for ketchup and sauces.
I do like the disease resistance, but since I don't sauce, I prefer a dual purpose tomato that is good fresh as well. Some people like tang, but I do not and I would like more sweetness. I have bought a lot of tomatoes that sounded good, but I learned to look for key words in the description from the seed seller. The seller wants to sell seeds, so they will tell you the good points about the tomato, but you have to look other places that are not interested in just selling seeds to get a better picture of what to expect and to find out about the not so great features it may have.
No mention of taste, just disease resistance, probably nothing special for taste.
Good flavor= there are better ones out there.
Old fashioned flavor and tangy sweet= some people like that, I don't.
Excellent, superior = probably tastes pretty good especially if they mention standings in taste trials.
Any tomato described as 'pretty', red, round = probably bred more for looks in the market and not for taste.
Heirloom= check for disease resistance, may be an issue or require special care in some places like mine.
Heat resistant= A must for growing tomatoes in areas where summer heat exceeds 85 degrees regularly
What you won't find in descriptions from sellers of seed " seedy", tough skin, does not do well in heat and humidity. Prone to cat facing or large blossom end scar.
Happy gardening in Hawaii. Gardens are where people grow.
