For 1926, Ithaca Gun Co. introduced the New Ithaca Double (NID) with a stronger frame, new lock work and a rotary bolt, some not fitted as well as they should be. The Field Grade NID was introduced at $37.50 retail.

That same year the Godshalks moved the A.H. Fox Gun Co. into a new more efficient factory and dropped the price of a Sterlingworth from $48 to $36.50 a dollar cheaper than a Field Grade NID.

The price of the Sterlingworth remained $36.50 until June 1932 when Savage upped it to $39.50.
