Hi, Stephen
It is probably a typo in the JaPo book, pls see this record for 210105:

I have no record of damage to 210103, which COULD point towards the aircraft being lost destroyed or abandoned after February 25th, the date for the last entry that is reported in the available documents from Gen.Genst.6.Abt.
Regards,
Andreas
