Looked a long time myself for a good clean M12 16. Found 1 early last Dec 885,xxx range 1941 solid rib 28" full choke about 90-95% condition. Got it fairly cheap. When I was at the Sioux Falls,SD gunshow 2 wks a go I saw 4 more 60-95% condition From $700-$1200 price range.The $1200 one was a honey and had a modified choke. I been shooting some 16-23 yd trap with mine. These solid rib models shoot as high as a regular trap gun. goodluck MB
