The great bulk of the Sterlingworth "pin guns" I've recorded, and all three I own, are rather hefty 30-inch 12-gauges. Top a March 1910 vintage The Sterlingworth Co., middle 1912 vintage and bottom 1913-vintage ejector gun --
When the Sterlingworth came out in 1910 it had a price of $25. For 1916, the price was raised to $30 and climbed to $55 by 1919. A.H. Fox Gun Co. reduced the price to $48 in 1922 and again to $36.50 in 1926. Workmanship of course declined. Savage kept the $36.50 price until June 1932 when they upped it to $39.50. On February 10, 1936, they upped the price again to $42.85 (the digits 2 and 8 are transposed in McIntosh's book). On February 1, 1938, Savage tried a price cut and dropped it to $35. February 1, 1939, they upped the price to $44.75. January 2, 1940, up again to $48.50. January 2, 1941, up to $52.65 and June 16 up again to $56.50. January 2, 1942, up again to $64.95.
