Topgun, the matter boils down to an appropriate (personal) definition of 'American Classic'. First it has to be classic, so that cuts out CSMC and Winchester in my mind. Then classic must be further defined by quality which is very much in the eye of the beholder. Finally, classic must have been widely distributed, successful, and long lived, although that might have weeded out Wilkes-Barre if I'd been unsuccessful in ever finding one.
I'm not much familiar with the other guns mentioned in your post, but I had a N. R. Davis which contrary to its advertising, was not "as good as the best". I think of Tobin as Canadian, H&R as pre-fab British, Hollenbeck et al as precursor to other American Clasics. De gustibus non est disputandum...Geo
