My friends Ithaca is a 12 gauge. Family history said his great uncle special ordered it from the factory, to be very light. It was light as a feather and choked full and full. Short stock, which I suspect had been hollowed out. He took it with him when he lived in China as a missionary. Unpleasant to shoot a round of skeet with. But it has remained in the family for over a hundred years. I admire that type of family loyalty.
