I got a tube of 5 atmega328-PU with the same numbers that's on both of my real uno.
I go to burn bootloader the ID shows wrong part the last number shows up 0x14 not 0x0F as it should now heres the funny part I change avrdude.conf to use this id burn the bootloader go to test a blink on them and guess what there now a 0x0F part thats not to happen bootloader can't change part numbers.
So I now have 5 that works as they should showing the right part.

But what really get's me is these have the same number atmeg328-pu and the atmel 1945 at the top as my real r2 uno
The real r3 uno has a atmeg328p-pu
