Earlier this year I bought 24 heritage tomato plants from a specialist nursery in Downham Market for a fiver They had no labels, so we don't know the varieties.

This one is pure gold! Soft and sweet, full of flavour but not too acid. I'd like to grow them next year but in case we're too greedy to save any seed ...

Could anyone identify the variety please? It's slightly paler than in the photo, pale lemon yellow rather than orange/gold yellow, and all of the fruit have that bump on the bottom.
