I have a pure Nitro Special 20 ga. mfd. in 1926 (I'm told) which is unmarked except for chokes 2 and 4 (mod. & full) on barrel flats. Only markings identifying the gun are Western Field MW&Co. on sides of frame. Without question it is a Nitro Special and not a Western Arms Long Range. Will post a few photos this evening since my son is in from Durango. He is camera literate; I am not. Chopperlump
