Yes, it's an older SP barrel. Like Tom, I can't remember the name either. They offered them for a short time as well as a stainless version of the All American (like what Tesko has for sale). If I remember, the one like Tesko's was just a Stainless AA and the one like this one was called a "Stainless Beauty".
Here's a link to them on PBReview: http://www.pbreview.com/products/reviews/219/ http://www.pbreview.com/products/reviews/217/
