Hello,
Another french serial related request I'm afraid.On delcampe there is a Nieuport serial No.8300 at:
https://www.delcampe.net/de/sammlero...893694091.html
I imagine that its one of the Nieuport 80 series trainers, in fact I'm almost tempted to opt for Nieuport 83 just because of the No.8300, but recognise that this is too much of a coincidence, so I'll avoid making an uninformed guess.
Regards,
Clint
