Hi nizlay! I found this post particularly interesting, as I have an Old Petra Sloane which looks exactly like the one posted. Now I am wondering whether my OP Sloane (purchased from Bluefly) is fake. I have seen so many Sloanes IRL I thought I would know if mine was a fake, but it looks exactly like the one lawbabe posted. The pocket lining of my OP Sloane is in some canvas/cotton like material (definitely not suede). The back of the zipper is riri M4 too (as in the picture of the fake). However, the dead giveaway to me that the bag might be a fake is the authenticity code - OP should be 2530. The picture has the color code for Noce I think......
