I keep getting the feeling that Galazan doesn't provide gunsmithing services for guns other than Galazan guns. Anyone have direct information on that?

I believe Galazan does offer a Fox style rib that is likely pre-matted. Of course that would require stripping the original rib and fitting the new one then laying it. Not a task for most but maybe if money is plentiful for the project, it can be done for a reasonable amount.
