Brian and I exchanged msgs today over this issue. He got BRIGHT YELLOW corrosion after only 4 hrs in the rain that left permanent pits in the case hardening that was I'm assuming redone by Turnbull when they redid the gun. Where are the metallurgists in the crowd here?? To me that indicates something very strange, something gone awry with the case hardening process. To a geologist yellow oxide indicates either sulfur, FeO in a particular form, arsenic oxide, bismuth oxide, or antimony oxide. Whatever it is, his gun is scarred and it will happen again if he doesn't take preventative measures. I recommended waxing it but that's a bandaid cure. Anyone have a clue what the issue is?
