Any sharpness/acidity to the berry flavor? How rich (brown sugary) are they?
I agree with Pete that this looks like what people typically refer to as a "Mt Etna" fig (the mountain in Sicily) - those typically have five lobe leaves with a few frills, fruit no larger than an old silver dollar, dark skin, dark interior, just like what you picture above.
I'm not willing to commit to it as a "final answer", but this still reminds me of Hardy Chicago, especially if you look at that full-grown leaf hanging near the base of the trunk - the 2nd set of lobes on HC are often smaller and jutting out at a hard angle like that.
The fruit size, shape, color matches a lot of "Mt Etna" types.
