Fox Collectors

Have a 20 ga. A Grade whose right ejector guide pin has come loose from the ejector. Took it to a Boise gun shop that had repaired the same problem in my 12 ga. A Grade several years ago, altho it took them at least 3 times. The gunsmith that did that job has apparently moved on and the fellow that worked on it this time couldn't get a weld to stick, and was afraid of ruining parts if he kept going. Idaho gunsmiths experienced in classic American side-by-sides aren't easy to find, so I was wondering if anyone has a suggestion for a shop that could handle this repair; in Idaho, or elsewhere?

Thanks

Mike
