Bumbellybeak, there are many and myself included that think the pre 1913 guns are made much better to the post 1913 guns. The workmanship was better.
Also in finding a 16 ga 2E Grade with two barrels I think is a great find. I quess I misunderstood your original question, I thought you were selling not buying. What is the asking price for the gun? I'm sure that whomever is selling it should give you a few days inspection to make sure ecerything, mostly the barrels are in good shape, especially the Damascus ones and that the chokes aren't polished out.
This gun with the ejectors would have been speecial ordered, so maybe the chokes are different than full/full.
Also the steel barrels would be Crown Steel and that should be stamped on the underside of the barrels. The Damascus barrels would be Chain Damascus. There were 12,887 No 2 guns made and 5,044 were Automatic Ejectors.
It's also possible that this gun might have what is called a "Joint Check", claimed to stop the rotational movement of the barrels around the hinge pin during opening of the gun.



This is the first style, if the one you are looking at has one it will probably be the second style with a pin instead of the rotary pin. Can be real nasty to take apart if the spring breaks in the joint check of the second style.
