I have recently aquired a 12ga. model 1912 s\n 78xxx. The barrel is 30" FULL choke. I believe it is a field grade because it has a plain barrel and stock. The metal finish on the reciever is a brownish rust color but not pitted. The barrel and magazine tube is a faded blue color with areas that are worn to bare metal on the magazine tube. I would like to know an approx. value as is and if professonal reblued\restored.
