Most of them have through the years been have been sold or merged, no longer a family business.
Remington is not a family owned business, was a corporation almost a hundred years ago.
Colt has been a corporation since 1836.
The current Henry started in 1996
I am surprised you didn't mention AH Fox, then again it was incorporated long ago, kind of died off and now is a really high end custom double barrel.
What I was saying, that I must agree with the original opening post by Rossignol, to the word "Family of firearms."
I never considered a corporation of investors a family even though they still use a family name.
Quote from press release by O.F. Mossberg from the company web site follows,
"Oscar Frederick Mossberg and his two sons, Iver and Harold, founded O.F. Mossberg &
Sons, Inc. in 1919. The company has remained a family owned business to this day,
and is the oldest family owned firearms manufacturer in America. Since 1967, Oscar’s
grandson, Alan, has driven the company to the success it has enjoyed over the
decades. Today, Alan serves as Chairman-of-the-Board, and his son, Iver, now
presides as the company’s Chief Executive Officer."
Maybe to be more precise we should rename this thread to "O. F. Mossberg and Sons, the oldest family owned firearms company."
