I may be totally wrong but I believe that Sutton was a sub-brand from Royce-Union bicycles out of NYC/Long Island. It was their upper end line of bikes, which is saying alot . RU sold a full line of kids to road to ATB bikes on the East Coast. Their quality was just a cut above department store bikes, but they fit the low end for independent bike shops. I am sure someone else will put in their 2 cents, but I am pretty sure that this was the fact. The Sutton was made in Japan and had nice parts and quality. Never saw many around , though. And, as you noted, the head badge was very ornate.
