I don't think it is a Clyde Slide since he did not jewel his aluminum although it is built the same even down to the flat bottom on vertical piece that the recoil pad attaches to. It is not one of my Slick Slides but they are all very similar in the way they are built and function. With the recoil system, padded comb, recoil pad pate and pad the cost is about $500 to have one done. Hope this helps.
