This is an unknown from Philadelphia that was distributed in the spring of 2014 by a member of the 'other forum' as rescue cuttings from a tree that was being cut down by a new home owner. This is a productive purple fig with a red center that clearly seems to belong in the Mt Etna class of figs, but for me has had a few features that make it stand out. Often it has been earlier than most Mt Etnas, and the size seems just slightly bigger than my typical Mt Etna.  In 2020, the first year that it produced fruits as an in-ground tree, all of the figs had a superficial, slightly cracked appearance appearance of the skin similar to the fig picture posted in the second link 'Unknown Abington Lives On'. It seems as hardy as other Mt Etnas, surviving its first winter in-ground with protection and fruiting well. Also, when grown in a pot, it did produce a few breba during two out of five summers.
