Rupiah, Good job reading those tiny numbers from my junky photo!
The 200 number that are "skipped" are simply printed a another PN correct? Wou be interesting to see a 3D image of all PN with 200 layers showing the serial increments.
I will add that in all of the notes the fpn was the same number as the bpn.
Finally found an interesting serial today, CDA5351535, a radar repeater!
