N73839

This time I thought this is an easy one from the Krul archive. Just go to the FAA site, insert N73839 and you get the type. But not a bit of it. “N73839 is not assigned/reserved” says FAA. Although it seems to appear faintly like a watermark on the fuselage. Googling also showed no success.

But what the FAA and Google don’t know, the experts of Forum Keypublishing do, don’t they?

Thank you for answers!:)
