From my research a few years back, it is most likely that these are ficus carica, a Smyrna type. The leaves do have a certain look for sure but appear to have a characteristic look that is similar to some caprifigs and seedlings of Sari Lop (that I have grown), the great Turkish fig variety used in dried fig production. Sari Lop, aka Calmyrna (over here in the States), is a Smyrna type fig.
