info request on ithaca hammerless double

chad carroll
I have an old ithaca double that I want to shoot, it is 12g boxlock ser#135675 with steel barrels (not Damascus)with ejectors. On the watertable on the reciever is stamped an S over a 12, on the flats under the barrels are stamped a 4 on one barrel and a 2 on the other (along with the serial # that matches the reciever)on the muzzel side of the 2 there is stamped 75 (off the flat), and lastly there is a p and f (or another p its hard to make out but they are differant letters) on the tab that the forend clips on. The barrels are in very good shape (no pitting or dents) and a 2 3/4 inch shell drops right down flush (doesn't seem short chambered). Also when the gun is un cocked the firing pins protrude thru there holes and are under spring pressure (the tumblers I presume) is it going to damage the pins if it is fired and the pins drag on the primers when it is opened?
Any information would be greatly apreciated
Thanks in advance

    Hello Chad...

    Your old Ithaca was made circa 1910 (I don't have access to my serial number listing at the moment, so I might be off by a few years). The chambers on that gun are not 2-3/4", but are most likley 2-5/8". The reason that a 2-3/4" shell will drop right in, is because it is not 2-3/4" long until it is fired. I strongly recommend against shooting it with ANY modern made 12 gauge ammo. Modern ammo creates a much higher chamber pressure than the old stuff did, and if you shoot 2-3/4" shells in those short chambers, it will push the pressure even higher (and kick the snot right out of you at a bare minimum), and it could bluge or split the barrel right at the forcing cone. There is nothing wrong with the way the firing pins are working in your gun. At the exact moment when you open the action to eject the spent shells, it recocks the hammers, which allows the firing pins to move freely.
