CMV on Tommy Toe?

[Labradors2]

This is a big healthy-looking plant, except that two of the side-shoots have developed stunted and deformed leaves as shown. The last picture is one of the whole plant which looks pretty healthy overall......

I've tried to search online and found some links here. Is this the dreaded Cucumber Mosaic Virus?

I really don't think this is due to chemicals since we don't use any, and our neighbours are not close. Tommy Toe is flanked by other tomato plants who all look healthy.

Thanks for any help with this. I'm biting my fingernails with worry!
