2 inch, 12's, if they weigh less than 5 1/2 pounds, are fine little bird guns. Of course other sub gauge guns can do what a 2 inch can, but that is beside the point. As already stated, most were made by Skimmin and Wood for other makers but I have seen at least three 2 inch, 12's made by Holland & Holland. I would stay clear of any 2 inch gun that weighs in at 6 lb. or more, such as those made by Arrieta. At $7K, those Spanish guns are too expensive, too heavy, and can't hold a candle to the quality of an older English gun. If you are really interested, keep looking and you will find one eventually, but be prepared to pay at least $5,000 for a nice, original boxlock and much more for a sidelock. They are among my favorite guns to take afield.
