What kind of work do you need to have done? Parts replacement or actual machine work? Looks like parts are still available, don't know how much "fitment" is required. I don't have any specific recommendations about gunsmiths but here's some links that might help on a start to your search. Many of the old line gunshops/gunsmiths don't have much of a online presence so you may have to distill what folks are saying in the forums about who they would use. Most of the forums have sponsor lists too which you'll probably have to join the forums to access that or member info. Hard to tell who are actually 'smiths without reading their profile(s). Lots of DIY'ers. Good luck, let me know if I can help.
