My uncle's early NID 16 "Star Model' w/ejectors and cocking indicators came with 30" "full and fuller" barrels. He bought it cheap in a store in Long Beach, California in 1938 after the person who had orginally ordered it failed to pick it up, and it sat there unsold for about seven years. Long-barreled small-guage doubles with TIGHT chokes seem to have been the rage in Southern California at one time....My uncle never used it for anything but to blast rats and crows--it and a Colt "pre-Woodsman" and an old nickeled Benjamin air rifle were his "arsenal." Now that I think of it, that isn't a bad arsenal for a practical fellow (non-gun-nut) to have. (The 16 is now IC and full and I use it for more traditional purposes, like pheasants, ducks and informal trap--my brother has the Colt; maybe the Benjamin was buried with Uncle Ray!).
