I have Howland Patent No. 1,818,852 filed June 18, 1928, granted Aug. 11, 1931, as the Selective single trigger patent. Two patents, No. 1,889,049 filed Nov. 30, 1931, granted Nov. 29, 1932, and No. 1,987,402 filed July 13, 1932, granted Jan. 8, 1935, appear to apply to the non-selective trigger. It appears Ithaca Gun Co. only offered the selective trigger on their Ithaca doubles but the non-selective was offered on Ithaca, Lefever and Western doubles and was offered retro-fitted to Flues Model Ithaca doubles. I have the non-selective on an NID No. 4E 12-gauge skeet gun and a Lefever A-Grade 20-gauge skeet gun.
