One of my late Grandfather's hunting and live pigeon shooting partners had a NID with the "snail ear cocking indicators" a 4E or perhaps higher grade 12 with 32" barrels, double triggers and ejectors-he used it for ducks, pheasants, dove and pigeons- don't know how it was choked, only say it a few times as a lad-but the wood to metal and the checkering was extremely well done-and he was a bachelor- treated that Ithaca like his first born-I believe he also had a high grade Knick single trap- but never saw it- his name was Noble Houck-wonder where those fine Ithacas are today-I'll love to own an Ithaca- saw a field grade NID 16 at a area gun show about a year ago-a "walk-around" for sale scene- rather than at a dealer table- asking $900- 28 inch barrels with DT and ejectors- looked almost Mint-don't know enough about that to know if it was refinished-but the balance and handling- owner said he though it was Full choke in both barrels, but I had no 16 ga. choke gauge with me, and here in MI the 16 has a small following- when I was station at Ft. Bragg (later Ft. Benning) many years ago, many of the base civilian employees would take us dove and or quail hunting, and I saw a lot of 16 L.C. Smiths and Ithacas being used-and used very effectively-great shotguns, all of them!!
