jdsfrance, I don't believe it requires pollination but will need to fruit it myself to confirm. I'm pretty sure Mark Albert does not have a caprifig and believe fruit set would be light without one in his yard. The Dauphine on the F4F variety list has 3 lobed leaves.
Vita, the Brogiotto Nero on the ficus carica site are solid dark black when ripe so that does not appear likely. Since the varieties given to Todd were different, I don't believe it's likely the same variety would have been given two different numbers by Todd (i.e., 258 and 376). The neck on 258 seems thicker than 375 and I don't see much of a stem on 258. Also, 258 leaves are not lobed as much as 376.
Thanks for your continued help and interest!
