I realize the map is small and difficult to read, so let me help you. I believe you can recognize lines 2, 3, 4, F and the northern section of line 1 by their description alone. The southern section of line 1 (and possibly the western border of the Julian March - see the previous post) is the dotted one that goes south of Udine. J and S are the ones that go deep into Italian territory. I is the one that grants Italy most of the Julian March. A and B follow the new border in the north and then partition Istria, with A being the line more favorable to Italy. Note of line F: I'm not sure if the original French proposal was meant to create a Free Territory of Trieste or grant all its land to Italy.
The map contains 2 errors:
1) The Treaty of Rapallo did not grant Fiume to Italy but joined it with neighboring Susak into a free state, which was dissolved 4 years later when Italy took the former city and Yugoslavia the latter.
2) Opatje selo/Opacchiasella, an exclave of Zone B within Zone A that can be seen on the previous map, is not shown.
