I have a Flues grade 1 in 20 bore- made in 1912 and looks like NRA VG- 28" barrels choked 2 (mod) and 4 (imp mod) and I use RST 2.5 ;ight loads in it- the Flues guns are a tad lighter than the later NID- remember, Lou Smith revised the basic NID 10 into the 3.5" cannon 10 Mag (Elmer Keith's favorite fezzant shotgun- but then he used a .44 S&W to kill corn crib rats too) The flues guns are great in the 20 and 28 gauges-just use light loads- I have a later (1919) mfg. Grade 1 12 Flues with ejectors on lay-away-- 28" No 2 right no 4 left- Ithaca was astute in marking their chokes with a numerical system- good barrels, and great locktime-Keep that nice old ten- and get those 2 & 7/8" RST's for it--
