What length are the barrels? You should stay away from steel shot entirely. Use bismuth, Nice-Shot, tungsten matrix, etc.

From the old serial number chronology, which may or may not be very accurate, your gun would be of 1927 vintage. Here are the Sterlingworth pages from the 1927 A.H. Fox Gun Co. catalogue --

The A.H. Fox Gun Co. shipped a lot of guns to L.H. Hagen in Christiana, Norway. A couple of pictures of the L.H. Hagen store from 1908 --
