Thank you, Drew for your informative post!
After reading it, it appears to me that my grandfather found one of the best low priced shotguns to give to my dad. It has fluid steel barrels and simple yet tight lockup.
My dad always honored his father, who was the town dentist, and his father was very proud of his son who fought in WWII and became a pilot for Pan American World Airways in late 1945. He fought in North Africa. He started flying C-47s (DC-3) and ended up driving the Boeing 747. He had a great career.
Look how proud my grandparents are of their flight student son, Harold E. McCarty, an only child. This pic was taken in 1942. His mother, Ruth, is so proud she could burst!
