I've got a couple almost identical guns by Walter & Charles Ogden of Owego, NY ( and one by their worker & successor Abe Williams). Using the "off the shoulder" firing position, they fit comfortably. Typical distance from the front trigger to center of the buttplate is about 13 1/4 inches. but they would "customize" the stock & fittings for customer requirements.This distance is similar to some other New York State guns that I own
