Dave-
Fantastic find, that one sure looks mint! I have lots of questions. What are the barrels like internally? What barrel length did you find? What's your SN, mine is 24XXX (curious to see if your gun is older, newer or of roughly the same vintage as my shotgun.
It might simply be a shadow in your photo, but it looks like your right hammer screw needs to be tightened down. If your shotgun is like mine, you might want to put some thread sealer on the screw while you are at it. I am eager to hear how it shoots for you, so do please update after you have had a chance to shoot it. Your shotgun with fluid steel barrels is probably a little stronger (and lighter) than mine, however, you will want to treat it to light loads nonetheless (for the sake of the wood if for no other reason). I will bet the shotgun will give you a lifetime of service.
