OK so I have not found any in detail info aboutthis model other than it was brownings 1st model with a slide, built for 11 years and about 750,000 or so made. So far from what I can see is it needs a safety spring, grips and a new action spring. Although it functions I found a small piece of spring when I removed the slide. The barrel is ok for its age with some muzzle wear. I have considered browning for a redo, but their customer service on my shotguns has been less than acceptable. So waiting a half century for them to redo is not in my desires. View attachment 9172
