Not only was there a problem with the Superposed, but for a while they tried to cure furniture wood with this method. Years later fine furniture started falling apart because the screws rusted so badly...... I agree with the process of getting rid of the wood all together. Or better yet, do what a lot of people do..... check the serial number before you buy the gun, and anything close- avoid it like the plague. Even if you spend the money to replace the wood, you will have a hard time selling it because people won't want it- either because the wood is bad or the wood has been changed and they will wonder what the inside of the gun looks like. They aren't worth fooling with. The Superposed is a pretty hot item right now at the gun shows. I sold two within 20 minutes of walking into the building. And the plain 20 gauge is nearing $3000.00 in nice shape. So if there is ever a chance of wanting to get rid of it, avoid the salt guns. JMO. Good luck.
