After falling and knocking a chip off the toe of my Model 42 Winchester, I drove to Hillsboro Missouri to Art Isaacson's Gunsmithing. He modified my grandfather's 16-gauge Auto-5 many years ago to use the longer modern ammo, so I figured he was the one I wanted to work on my little .410. Not cheap but I trust them. Here's what I learned - Browning no longer services A-5's. Parts are to the point Art is stripping out some to fix others. Repair/restoration orders at his shop are backed up to about 300 jobs with three men working when I was there. Several hundred A-5 barreled actions were neatly hanging on hooks, re-blued, awaiting assembly and stock work. What I saw was very well done with attention to detail . 2-3 month wait due to the volume. The shop is located behind the house, about 45 minutes outside St. Louis. Nice fellows to talk with and he does reply to emails.
