I Google'd Castelvetrano airfield, Sicily and found this image of the large type 2 Y shaped a revetment located Trapani-Milo.
So I decided to do a little aerial reconnaissance and found.....
From these remains I should be able to work out the dimensions and wall thickness for this type of revetment, from the start these pens seem more Y shaped than the the photo interpreters drawing key.
All around the boundaries of the airfield there are numerous piles of scattered rocks, and the odd depression, no doubt remnants of other demolished revetments.
Here's the google map reference, if you want to have a poke around for yourselves:
