Identification of Tomato plant?

Anyone able to identify the tomato variety in the photo? I grew these last year and they were lovely. The plant grew around 2-3ft, the tomato fruit I believe was a plum type and were sweet?

 

I've grown San Marzano which might fit the bill, but there are others, like Romello.

 

Whatever it was, you can't give it a name based on similarity to certain variety, unless you find seeds pack, and seeds seller advised you on the name. Just a name to use by yourself
There are thousands of tomatoes varieties.

 

Yes.
I believe that I have found the tomatoes which is Patio Plum Tomato RHS AGM.

 

Its got weird leaves.
