I bought this 20 gauge in a recent moment of weakness. Wards Western Field SB60A. I have never seen an extended forend on any Stevens 520/620 pumps but this one looks like it would have been original. Look at the triangular checkering pattern like other Stevens forends. It was the butt stock that sold me on it though! Did words make higher grade guns like this as factory original? Could this be someone's 50s skeet gun?
