Welcome dlbshooter,
I tried to research the guns when i had my 20ga and found next to nothing. They are wonderful little guns but way to light for me at 5lbs. They were available in 12 and 20ga. You will find both pistol grip and straight grip guns with single or double triggers. A&F did import them but you will also find older guns with no import marks. The guns were available with (ASEL) or without engraving (ASE). Renato Telo still makes a boxlock of the same design. Best-JB
