Read Thread: Wrong stamp in box...Solutions?
There's a boxer named Christian's Christian on AQ.
They haven't had any logged finds in almost a decade, and nothing even remotely close to that box, so... highly unlikely to be them. Nice sleuthing, though! It seemed, based on the info you had, to be a good possibility.
Did you reach out to Birdwell? They might have done a little digging, too. https://www.atlasquest.com/showinfo.php?boxId=255065
