Tom, thank you for your input and opinion. I'll get more detailed pictures of the 2 sets of barrels. As you mentioned the fit of the 20ga barrels is incredible, regardless of the origiion of the 2nd set of barrels do you know of another multi gauge LC Smith like this one ? In my opion these barrels are very well made and are meticiouosly fitted to this gun, someone really did their homework when they set out to achieve the task of making a multi gauge LC Smith. As good of resources and technological we have at our finger tips today it couldn't be done, look at Galazan and other gun builders of today that have tried to venture out to achieve what this gun stands for. Please feel free to post the pictures JohnLiles sent you on this site. John assured me you'd be the best one to tell us what this gun really is. Thank you for your information
