Neat! I have a whole bunch of variations of these rifles. The first one I bought was a Savage 6AB, found in the basement of the old E&D Sports in Maple Ridge, years ago. They are a neat rifle to shoot. There is a thread on Rimfire Central that records and deals with the many variations.
I have one that is a quasi clone/copy of this rifle, but nobody has been able to put a name to it. I will keep my old 6AB and the clone, but will probably let the rest go.
