How interesting! I'm no photographer either, but can you get the pics into focus a bit better? Is there tooling marks, obvious scrapes or anything? Or does it just appear to have been smashed?
The first thing that comes to mind is that the parts kit was simply damaged during shipment, as it is sometimes disassembled. . . does the firearm function properly? Gas tubes can be had for cheap, so I'd order a new one. That's out of the ordinary for sure!
What importer is the gun from? Century? If so where did you pick it up from?
