I don't know for sure what that thing is, other than you probably don't want it. There was never a .500/.475 cartridge. The seller says this gun uses a .470 case with .483" bullets. No, I don't think it's been rebarreled. The proof marks on the flats are for the .475 3 1/4", which uses .483" bullets, and is based on the .450 case. I'm pretty sure that this rifle is just a .475 3 1/4" that had badly pitted chambers which somebody cleaned up with a .470 reamer, resulting in a wildcat. Call it a ".500/.475" and presto, it isn't a buggered gun anymore!

The "barrel reinforcements" aren't that at all. Those are the wings of the shoe-lump assembly. Rodda seems to have used shoe-lump barrels almost exclusively. No, the wings don't follow the contour of the fences perfectly, but that's just the way Rodda's look.

That thing is gonzo over priced.
