Is this tomato blight, if not what please?

@JWK Remember the black stem patches on tomatoes in 2012, that didn't appear to be like 'normal' blight, but the RHS tested a sample and confirmed it was blight?

Is it Verniculum wilt?

 

I have the same thing on my Russian Black Seaman tomatoes. Apparently it hits in the fruit stage. Mine happened quite late on so I should be fine. Growth will just be stunted from now on. Ois a beast anyway about 5'8" tall with a lot of fruit. My other has suffered a bit. Pots will need bleaching, but I'm trying to find ways of treating the soil and not throwing it away. Its expensive!
