This non selective Hunter One-Trigger was $11.00-$18.00 (depending on grade) option when offered in 1934. Compared to the selective one for $25.00-$33.00 To tell you the truth I believe that in the forgings, they were all made for two-trigger guns, and this forging was made seperately. I could be wrong.
The book says it is identical except for the selector slide. Now we know better.
