Bull Tomato Plant?

I purchased two tomato plants back in May. One is growing excellent, flowering well and some tomatoes are growing. The other plant nothing is happening, no flowers although the plant seems to be healthy and larger than the other plant.

I have read that I may have a "Bull Tomato Plant" apparently these plants do not flower, is there any way I can tell if it is a bull type plant? Picture below of the dodgy plant.

 

Personally I've never heard of non flowering tomato plants.

Yours looks like its got either some insect damage, or possibly a virus.

 

Thanks for the advice. To be on the safe side I have binned the plant.
