Centenary Of South Australia 1934

Hi to all

Whilst looking through more of a collection I purchased, I found these two Centenary of South Australia stamps.

The top upper left corner shows a week frame or a break.

So far I have found two. However, is this the retouch listed in ACSC ( I am working from a 2007edition till my wife buys me the latest for my Birthday later this month.) All others so far have a erfect frame.
With two exactly the same, it would seem that it should be a constant variety. Also above the tree on the left hand side, is that the retouch variety mentioned in the catalogue.
