Up till now I wasn't sure what variety they were, but I presumed they would be either "Maskotka" or "Montello", which were the two varieties I grew in that location last year. One of the plants produced a couple of fruit very early on:-

From the shape of the fruit, I was able to determine that these were definitely NOT "Montello", which has plum-shaped fruit. This year I have one "Montello" plant out there, whose identity I'm sure of, because I grew it from seed. Its fruits are just turning colour now.

Since the mystery plants were not "Montello" I jumped to the conclusion that they must be therefore be "Maskotka". This would have suited me just fine, because this is my favourite variety of small-fruited tomato.

Well, the plants in question have been growing away steadily in that spot below the kitchen window - a very good spot for growing tomatoes, by the way, since it gets most of the afternoon and evening sun.

All three of the mystery plants have set quite a lot of fruit, and it is now beginning to ripen. As it does so, it demonstrates that these are not "Maskotka" either. The way the clusters of fruit are arranged is different, and most obviously of all, the fruit have dark green shoulders before they ripen, which "Maskotka" does not.
So, realising that my original assumptions are completely wrong, I have been back through my records and I see that in 2017 I grew "Losetto" in this place, and the characteristics of both plant and fruit fit this variety. So the seeds that germinated in October 2018 had been there for at least a year!
This plant in the corner is definitely a "Losetto".
I'm still not convinced that the other two plants are 100% "Losetto" though. Their fruits are much bigger - though they still have the distinct green shoulders - and to me they look a bit plum-shaped. Maybe they are a hybrid of "Losetto" and "Montello"?
This has been an interesting experiment, but I still think I would rather know in advance what sort of plants I'm growing!
