Story
Here is another 4 layer reverse engineering PCB project.
TOP with components.
TOP without components
TOP without components and solder mask
TOP from SVG drawn by me.

Inner layer 1 .The glass textolite between the top and inner layer 1 has not yet been completely removed.
The glass textolite between the layers is thin and becomes almost transparent.
The glass textolite between the top and inner layer 1 has been completely removed.
I have milled away part of the traces on Inner layer 1.
There is always such a risk - that's why you should scan slightly before reaching the inner layer.
