Nope not brass.
The Single Six was sent to Mag-na-port. What I really wanted done was an action job, recrown the barrel, chamber the other end of barrel and number the chambers. Kenny wanted to do the plating job and jeweling as well so I said go for it. The plating is titanium I believe he said. In hand it has a gold colored appearance but yes I can see how in the photos it could be mistaken for brass.
The grips came from Altamont Grips
http://www.altamontco.com/ the price is $28 per set and the scrimshaw work added $30 each for a total of $58 per set plus shipping. I think my total bill was $125 and change if I recall correctly. I had them within about a week or so of calling my order in to them. They have a toll free phone number. From what Doug said they make a lot of the grips for Ruger that they put on the guns and that they sell for aftermarket as well. They cost less direct but they can't put the Ruger logo medallion on. I asked and he said nope couldn't do it.
Heck Richard call Doug up and ask him if he can make some for your Uberti's. He might can even if it's not cataloged. I don't know that am just saying it don't hurt to ask.
