Bonny's Best? I got them from "Baker's Creek Heirloom Seed Company" I grew it in 2014, but it did get a lot of the tomato diseases, so I didn't use it this year. Big mistake! It was great tasting and a huge producer. I still have tomatoes in the freezer. They weren't huge, but had the real old tomato taste and had a tremendous amount of tomatoes. I needed 6 plants and planted 9 seeds, I got nine plants! I will be growing them next year.

Probably Sherry nailed it. Baker Creek says that it was introduced in 1906.

The description fits what you have said.

And the name "Bonny .." , a woman's name !!!

No, that's not it. It only had a one-word name. It was what they called at the time a "canning tomato," about 2-1/2 to 3 inches across so it fit well into a canning jar whole. I think it was determinate, but not sure.

I remember now why I grew it. I liked making green tomato pickles, and the slices were small enough to fit into the jars without breaking them.

Well, I got creative and looked up 19th century girl names and found it -- MARION. Marion tomatoes! I'm going now to see if I can find seeds anywhere, or if anyone here has been saving this seed forever, I'd really love to buy some from you.

I did find it. Not many places have it, but there are a few. It's described as "a Rutgers type" tomato, hardy to z9, which is where I am, so I'll try it. Bonnie Plants still grows it too, so I'll look for it next spring when the tomatoes come into the big box stores. It's really great for fried green tomatoes and also for green tomato pickles because it's meaty and tough. It used to be a commercial variety, but I guess they gave it up because it's susceptible to early blight. I'll grow it in containers to try to avoid that.

These are two places that have the seed

Several years ago, I asked my dad what tomatoes they grew on the "truck garden". He said, without hesitating, "Earliana and Bonny's Best". This year I grew each of them. Although they weren't the best of the best in terms of taste and production, they will always have a spot in my garden as a memory to Dad! Btw, my dad was born in 1925 in Missoula, Montana where he worked with the family on the truck farm. He stayed there until he enlisted in the Army Air Corp at the age of 18 in 1943. He passed away this summer at the age of 90... boy do I miss him!
