Top photo is Big Beef x EPB F6 grown in my patch in 2013.
Bottom photo is same line grown in a friend's garden, same year.
(The purple tomatoes in bottom photo are Not Purple Strawberry.)
Sorry my poor quality photo is from a cheap smart phone, and you cannot see the tiny white speckles in the skin of the fruit. This characteristic mimics or repeats from EPB. However, this line does not shatter (fall from the vine) when the full ripe, an improvement over EPB.
