the vintage ones tend to be less expensive and as you proly know one can get j.t. callahan letter. it specifies: grade, gauge, barrel lenth/chokes, stock dimensions, weight plus you get extra info. "your shotgun was completed.....on february 6, 1914.....abercrmobie & fitch of nyc.....re-sold on april 3, 1915 to the e.k. tryon co. of phila. pa.....it carried a price tag of $52.50 in 1914." at that price i would take a cartfull.
