In the last few years I have come to love Case Color guns, lever guns and SXS's. I always thought that Uberti did the real Bone colored hardening but have been corrected by others. They say everyone is using a chemical coloring now and most will fade with very little cleaning. Can anyone elaborate on this method and is it true everyone is using this process now. I have seen quiet a few Uberti's with what appears to be real bone colored case colors. I have seen pics of Turnbull restorations and they look the besr with the bone colors.
