This gun by the final inspestion report had the second set of barrels fitted in Oct 22, 1956. The final inspestion was completed on Oct 30, 1957. The gun is checkered and carved as model 21 catalog #2111. With 30" barrals mod. and full the second barrel is 28" WS1 and WS2. The carving is the old style B carving by Ned Schwing's book. The stock is Monte Carlo with both barrels having beavertail forearms carved in the old B carving. I will try to post photographs of the gun later today.
