The silkscreen ( components mask of above pcb's ) can be seen in below photo.
I wish to all members of diyaudio.com forum, a better New Year 2014 !

TINNED printed circuit board on XPC support ) thick 1 mm - copper 18 um
Advantages ( than FR4 )
-lower cost;
-better drilling and cutting;
-tinning is better ( more sticky and more uniform ) ;
-more accurate traces and pad's ( in special for pcb's done it from .jpg with low resolution <600 dpi
