Tasmanian Devils 01: 1/2 Lake Marion errors g

In my previous post, I have skipped the text frame 'LAKE M(arion), as there were too many flaws in the fields I3 and I4.
Now we can have a closer look at it:

There are a dozen flaws to detect in this area. Most of them occur in plate 1, some in plate 2.

Some flaws need to be combined with flaws in other positions on the stamp, in order to be sure of the correct position of the stamp in the plate.
