Ron Smith rebarreled and basically restored an early thickside Winchester 1885 for me a couple years ago. He worked his magic and the gun, whose former owner suggested that I throw it in the river as I crossed the bridge near his house, now shoots like a laser beam. I restocked it, but all the mechanical credit goes to Ron. Contact him by mail or phone (note: have a little patience as his hearing isn't that great) and discuss your project. His work is truly top notch. He is a master craftsman of the old school.
