Hunter Arms built 16 guage guns on both "Featherweight" and "Regular" weight frames. Early catalogs promoted 16 guage guns as light as 6 1/4 pounds before the Featherweight frame was introduced in 1907. Even after the Featherweight frame was introduced, ads still promoted lightweight 16-bore guns at 6 1/4 pounds; so, as previously noted, Smith frame type was not an accurate indicator of finished gun weight. I don't recall seeing a 16-bore on a Regular frame dated post-1920, and the early 16-bore guns build on a Regular frame are not common; but, in my mind, those models have better lines than the later Featherweight framed models in the lower grades. The lightest 16-bore Smith gun I have ever seen was built on a Featherweight frame and weighed in at 6 lbs/3 oz. That gun featured additional milling cuts and drilled holes beneath the lockplates (along with very plain wood) in a further effort to reduce final weight as much as possible.
