Getting the name would be a good starting point for this project.
If the entry point for these guns is in the $5,000-7,000 range, the guns will sell.
The only company I know of that could handle something like this today is CSMC. I'm not sure they would be interested in such an undertaking. If they put in the custom class with the Model 21 and the Fox, I have no doubt that they could product a limited number at a profit. With their experience and know how, I wouldn't hesitate to buy one.
Having said that, I have more SxS's than I know what to do with.
Still....
