Chuck,
Here is the link:
http://16ga.com/But, unfortunately I doubt you'll pick up anything practical about relaying ribs. Its mostly a discussion/argument about B. Rizzini barrels with a member who claims that small Italian firms other than Perazzi sell guns with bad barrels. Larry Brown and other guys who visit the forum will understand.
That's why I am becoming more and more interested in actually how barrels are made, why one kind of solder is used over another, and why they come apart.
The Parker project sounds fun! I went through a Spanish SxS phase and now restocked my safe with some B. Rizzini guns that I really enjoy. But the SxS bug keeps nibbling at my ear and I am sure in short time I am going to purchase an American SxS project gun --most likely a Fox or Parker. If its a Parker, I am sure it will be a damascus gun!
