Varieties can't be identified just from appearance so there is no way to know. It could be any one of 50 varieties. Just eat it and enjoy and don't worry about what it 'might' be.

If you think it's not a hybrid, you could save seeds from the current fruit and plant them. See the FAQs linked on the Growing Tomatoes Forum page for how to save tomato seeds.

You could also go to the big box stores in your area and look at the seeds they're selling this year. Maybe the same envelope that looked enticing last winter will catch your eye this year.

Or you could continue to plant cuttings.

Good points. I think I have 3 plants with these cuttings...

Once I figure out the yield I'll see if it is worth saving. RIght now they're in a colder than wanted (65-67 during day) basement, and they've taken nearly 90 days to give 10-15 tomatoes... with about 30 more on the plant now. Seems slow.
