Ring Ins and Wrong Labels

This year I dug up a small section of lawn to plant out a few tomato plants that I had, because I was short on growing space. One of the plants that found its way into this patch was a self sown seedling that came up in a tub with some Zucchini's, the tub and its contents having been used last season. I thought at first the tomato plant may have been from a yellow variety I grew in the tubs last year, but soon realised that this was a regular leaf plant, where last years were potato leaf. Today I picked my first ripe fruit from this plant, but I cannot work out what variety it is, so all I can do is call it a 'ring in'.

Here's a photo of the fruit.

The very next plant in this same bed as the fruit above, is also producing ripe fruit, but how disappointed was I when I saw the fruit shape and size, realising that this one must have been wrongly labeled and not the tear shaped cherry tomato I was expecting. I have since found that these could possibly be a variety called 'Ceylon'.

Here's a few to show you.
