Thank you!

I did choose other and private, but again it was rejected: Bad Info: Serial Number/CN.

I usually left this field blank when I didn't know the answer, as the rules require. Can anyone help me with this? Thanks!

Hi all!

I got rejected because of bad information:
https://www.jetphotos.com/viewqueued_b.php?id=9031021

There is no information on this aircraft in any open source. The upload guidelines say:
"The option "Unknown" should only be used, if there is no way to find out the correct airline." I believe that this is such a case.

Please help me with information about this plane that could help me upload a photo.
Thanks!
