You might check with Brad Bachelder- last time I was in his shop (to pick up a Winchester M53) I believe he had two 12 gauge graded Smith 12's, 32" ventilated rib, HOT, EJ.-- A Crown grade 12, a tad bit pricey for my budget, but so is a Rolls Royce Silver Shadow- but a man can dream. I'm not sharp enough to tell an upgrade from an original, whether a Smith or a Parker, so no comments on that aspect- RWTF
