Thanks for the welcome!Hi and welcome to the Purse Forum. I don't know PS11 bags as well as Ellie, but the missing letter does bother me (although, of course, such errors are possible). What do you mean by the different hardware placement, could you elaborate and possibly post more pictures of the d-rings? Thanks.
With that said, the thickness and feel of the leather can - and does - change from year to year.

It's probably like what Ellie said about a structural change with the newer one and I'm just hyper-fixating!
