Apparently smallbore doesn't "Dig" B-25s. Someone has pointed out that we are all experts or experts in the making. Jon has questionned the source of oxidation inside the u-channel of the frame described by Jimmy. I have seen two salt-era guns besides mine. One from which I ran--not walked--away had oxidation travelling onto outside of frame at intersection stock shoulders. The second, from which the wood had been removed, also showed corrosion on the face and shoulders of frame, sides of tangs, hammers, springs, inertia block, forend iron and both barrels (all the points of intimate wood/metal contact plus) but no corrosion in the barrel cradle of the action. Could be the real experts are the guys like myself who actually buy them. Having heard there's a fire across town is not the same as getting your skin blistered. I stand by my answer to Jimmy on his first trial balloon on this topic: "Why would you rain on the guy's parade when he hasn't asked for a weather report?"
