LewsTherin, I believe your Western Field Model 565-F is the same as a Noble Model 60 shotgun. Western Field was a trade name used Montgomery Wards on a variety of firearms. The Nobel Model 60 was made from about 1955-1965. This is definitely a field grade shotgun and would be considered a shooter versus a collectable. These typically had a full choke if not adjustable. Hope this helps!
