In 2016, I bought a D400 that came as :
- Expert 200 having s/n 0xxxxB1
- Expert Companion 200 having s/n 0xxxxxB0
[ wherein x are numericals ]
In 2018, I sent them for upgradation to 440-Pro CI and the serial numbers became
- Expert 220-Pro w/ CI having 0xxxxxF2
- Expert 220-Pro w/ CI having 0xxxxxF2
When they got upgraded from D400 to 440-Pro CI, the xxxxx numericals earlier when they were D400 did not change and those same numerical combinations were retained and F2 added.
