This gun is one (1) of three (3) Grade 1 20 GA guns with 26" barrels and ejectors. How many of these three had the Hunter One Single Select Trigger is unknown. Recording of that factory option did not begin untill 1918.
The Letter was packed with great information on my gun, Grade 1 guns in general and Hunter Arms and L C Smith.
Great job Research Division and Jim Stubbendieck.
