OK, I made my pictures and...
... had to notice that looking at the pictures my 2 domed and 1 flat were instead 3 different shapes.
So after I bought 6 T22 in total where I could instantaneous spot 3 non matchings (costy, but with overseaes shipping not worth to claim) I only got 2 originals and 4 reps sold as originals. Don't ask from which sellers I got them, but they are well known in the high cost Rolex sales...
Here are the pictures to compare:
First one is one I got as "gen flat", so later makes, second I got as "gen domed" so the earl makes and third one I also got as "gen domed" but this is slightly more domed as the second.
So for me the second seems to be a rep T22 which from shape is exactly in between the gen flat and the gen domed one...
Please correct me if I'm wrong.
